Guía de implementación de redundancia de HA CSR1000v en Microsoft Azure con Azure CLI 2.0
Contenido
Introducción
Este documento proporciona una guía de configuración paso a paso sobre cómo implementar routers CSR1000v para alta disponibilidad en la nube de Microsoft Azure con Azure CLI 2.0. Su objetivo es proporcionar a los usuarios conocimientos prácticos de HA y la capacidad de implementar un banco de pruebas completamente funcional.
Hay varios métodos para implementar imágenes en Azure y el método más familiar para la mayoría de los usuarios es a través del portal web. Sin embargo, AzureCLI es una herramienta rápida y potente una vez que está familiarizado con ella.
Para obtener más información sobre Azure, cómo implementar un CSR1000v a través del portal web y HA, consulte la sección Guía de implementación de Cisco CSR 1000v para Microsoft Azure e información relacionada.
Prerequisites
Requirements
Cisco recomienda que tenga conocimiento sobre estos temas:
- Una cuenta de Microsoft Azure
- 2 CSR1000v y 1 máquina virtual Windows/Linux
- AzureCLI 2.0
Componentes Utilizados
La información de este documento se basa en Denali 16.7.1 de Cisco IOS-XE®
La información que contiene este documento se creó a partir de los dispositivos en un ambiente de laboratorio específico. Todos los dispositivos que se utilizan en este documento se pusieron en funcionamiento con una configuración verificada (predeterminada). Si tiene una red en vivo, asegúrese de entender el posible impacto de cualquier comando.
Objetivo
Implemente 2 routers CSR1000v y 1 VM (Windows/Linux). Simular tráfico continuo desde el Data Center privado (VM) a Internet (8.8.8.8). Simule una falla de HA y observe que HA ha tenido éxito al confirmar que la tabla de ruteo de Azure ha conmutado el tráfico de CSR-A a la interfaz privada de CSR-B.
Topología
Para comprender completamente la topología y el diseño es importante antes del inicio de la configuración. Esto ayuda a resolver cualquier problema potencial más adelante.
Puede haber varias situaciones de implementaciones de HA basadas en los requisitos del usuario. Para este ejemplo, configure la redundancia de HA con estas configuraciones:
- 1x - Región (centro sur de EE. UU.)
- 1x - Grupo de recursos (CorporateDatacenterResourceGroup)
- 1x - Vnet (CorporateDatacenterVnet)
- Interfaces de red 6x (3x cara interior y 3x cara exterior)
- 2x - Tablas de ruta (InsideRoutetable y OutsideRoutetable)
- 2 routers CSR1000v (Cisco IOS-XE® Denali 16.7.1)
- 1x - VM (Linux/Windows)
Por ahora, el acceso a Internet a través de la interfaz pública se deja habilitado en la máquina virtual para que pueda acceder y configurarlo. Generalmente, todo el tráfico normal debe fluir a través de la tabla de rutas privadas. La interfaz pública en la VM se puede inhabilitar más tarde para que no se filtre tráfico accidentalmente.
La simulación de tráfico se realiza mediante ping desde la interfaz privada de la máquina virtual → tabla de rutas internas → CSRA → 8.8.8.8. En un escenario de failover, observe que la tabla de rutas privadas ha conmutado la ruta para que apunte a la interfaz privada de CSRB.
Diagrama de la red
Terminology
- Resource Group (Grupo de recursos): esta es una forma en la que Azure puede realizar un seguimiento de todos sus recursos, como máquinas virtuales y eventos. Esto se usa generalmente para administrar todos los artículos y para hacer un seguimiento de los cargos.
- Vnet: red virtual (similar a VPC en terminología de leyes).
- Tabla de rutas: contiene las reglas para una subred y puede reenviar tráfico específico a una dirección IP o actuar como un terminal VPN.
Restricciones
- La propia Azure puede introducir un retraso de aproximadamente 40-50 segundos en una falla de HA.
Configuración
Hay algunos métodos para implementar VM en Azure:
- Portal web: documentación de HA en cisco.com
- Powershell: modelo basado en la línea de comandos para administrar recursos de Azure.
- AzureCLI 2.0 - También basado en la línea de comandos. Es de código abierto y está escrito en Python y debe instalarse en su sistema local. Para escribir este documento, AzureCLI 2.0 es la última versión.
- Azure Cloud Shell: elija la opción Bash shell en lugar de la opción Powershell para usar AzureCLI a través del shell. No es necesaria la instalación de este método.
Powershell y AzureCLI son similares, pero los comandos para AzureCLI son más sencillos. Ambos pueden ejecutarse en Windows, MacOS, Linux. Consulte Elección de la herramienta adecuada para Azure y comandos de PowerShell y CLI de Azure lado a lado para obtener una comparación.
Para este ejemplo, implemente todos los recursos con AzureCLI o Cloud Shell. AzureCLI se puede instalar en MacOS, Windows o Linux con pasos ligeramente diferentes. No hay diferencia en la configuración durante el resto del procedimiento entre AzureCLI y Azure Cloud Shell.

Overview
Paso 1. Instale AzureCLI 2.0.
- Siga los pasos de instalación para Windows, MacOS o Linux en la documentación de AzureCLI 2.0.
- Para MacOS:
$ brew update && brew install azure-cli
- Inicie sesión en Azure y siga las instrucciones para autenticar su sesión.
$ az login
- Una vez completada la autenticación del explorador, la información de suscripción de Azure se devuelve en formato JSON:
[ { "cloudName": "AzureCloud", "id": "09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx", "isDefault": true, "name": "Microsoft Azure Enterprise", "state": "Enabled", "tenantId": "ae49849c-2622-xxxx-xxxx-xxxxxxxxxxxx", "user": { "name": "cisco@cisco.com", "type": "user" } } ] - Antes de comenzar con el resto de los pasos de configuración, aquí hay algunos comandos y consejos útiles sobre AzureCLI.
- Para obtener ayuda con los subcomandos disponibles y lo que hacen, utilice la opción -h.
$ az account -h
- Todas las salidas se devuelven en formato JSON de forma predeterminada. Para facilitar la lectura, puede utilizar la opción —output table para mostrar en una tabla.
$ az account list-locations --output table
- Obtenga una lista de todas las máquinas virtuales disponibles o reemplace la opción —all por una de las otras opciones siguientes para filtrar la tabla.
$ az vm image list --all --output table
You are retrieving all the images from server which could take more than a minute. To shorten the wait, provide '--publisher', '--offer' or '--sku'. Partial name search is supported.
- Consulte la documentación de Microsoft Azure CLI 2.0 para obtener información detallada sobre todos los comandos de configuración.
Paso 2. Crear un grupo de recursos.
- Un grupo de recursos es un contenedor que contiene recursos relacionados para una solución de Azure. Dé un nombre al grupo de recursos y elija una ubicación para implementar el contenedor. En este ejemplo se utiliza la región centro-sur de EE. UU.
$ az account list-locations --output table DisplayName Latitude Longitude Name ------------------- ---------- ----------- ------------------ East Asia 22.267 114.188 eastasia Southeast Asia 1.283 103.833 southeastasia Central US 41.5908 -93.6208 centralus East US 37.3719 -79.8164 eastus East US 2 36.6681 -78.3889 eastus2 West US 37.783 -122.417 westus North Central US 41.8819 -87.6278 northcentralus South Central US 29.4167 -98.5 southcentralus
$ az group create --name CorporateDatacenterResourceGroup --location "South Central US"
{
"id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup",
"location": "southcentralus",
"managedBy": null,
"name": "CorporateDatacenterResourceGroup",
"properties": {
"provisioningState": "Succeeded"
},
"tags": null
}
- Plantilla (adición de grupo de recursos)

Paso 3. Crear una red de ventilación.
- Una red virtual es un espacio de direcciones IP en el que se implementa la red. Este rango se divide en subredes más pequeñas y se asigna a las interfaces. Asigne un nombre a la red virtual, asígnelo al grupo de recursos creado en el paso 2 y asigne un rango de prefijos. Si no especifica un prefijo, Azure normalmente le asigna 10.0.0.0/16.
$ az network vnet create --name CorporateDatacenterVnet --resource-group CorporateDatacenterResourceGroup --address-prefix 192.168.0.0/16
{
"newVNet": {
"addressSpace": {
"addressPrefixes": [
"192.168.0.0/16"
]
},
"ddosProtectionPlan": null,
"dhcpOptions": {
"dnsServers": []
},
"enableDdosProtection": false,
"enableVmProtection": false,
"etag": "W/\"7c39a7a9-46e5-4082-a016-xxxxxxxxxxxx\"",
"id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/virtualNetworks/CorporateDatacenterVnet",
"location": "southcentralus",
"name": "CorporateDatacenterVnet",
"provisioningState": "Succeeded",
"resourceGroup": "CorporateDatacenterResourceGroup",
"resourceGuid": "3d95d732-e46a-4fae-a34b-xxxxxxxxxxxx",
"subnets": [],
"tags": {},
"type": "Microsoft.Network/virtualNetworks",
"virtualNetworkPeerings": []
}
}
Paso 4. Creación de Tablas de Rutas.
- Cree una tabla de rutas para las interfaces internas.
$ az network route-table create --name InsideRoutetable --resource-group CorporateDatacenterResourceGroup { "disableBgpRoutePropagation": false, "etag": "W/\"45088005-cb6f-4356-bb18-xxxxxxxxxxxx\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/routeTables/InsideRoutetable", "location": "southcentralus", "name": "InsideRoutetable", "provisioningState": "Succeeded", "resourceGroup": "CorporateDatacenterResourceGroup", "routes": [], "subnets": null, "tags": null, "type": "Microsoft.Network/routeTables" }- Plantilla (adición de tabla de rutas)
redundancy cloud provider azure 100 bfd peer route-table InsideRoutetable default-gateway ip cidr ip app-key subscription-id app-id tenant-id resource-group CorporateDatacenterResourceGroup
- Cree una tabla de rutas para las interfaces exteriores.
$ az network route-table create --name OutsideRoutetable --resource-group CorporateDatacenterResourceGroup { "disableBgpRoutePropagation": false, "etag": "W/\"a89b6230-9542-468c-b4b2-xxxxxxxxxxxx\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/routeTables/OutsideRoutetable", "location": "southcentralus", "name": "OutsideRoutetable", "provisioningState": "Succeeded", "resourceGroup": "CorporateDatacenterResourceGroup", "routes": [], "subnets": null, "tags": null, "type": "Microsoft.Network/routeTables" }
Paso 5. Crear subredes.
- Cree una subred /24 desde el espacio que asignó para la red virtual en el paso 3 y, a continuación, asígnela a la tabla de rutas internas.
$ az network vnet subnet create --address-prefix 192.168.1.0/24 --name InsideSubnet --resource-group CorporateDatacenterResourceGroup --vnet-name CorporateDatacenterVnet --route-table InsideRoutetable { "addressPrefix": "192.168.1.0/24", "etag": "W/\"a0dbd178-3a45-48fb-xxxx-xxxxxxxxxxxx\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/virtualNetworks/CorporateDatacenterVnet/subnets/InsideSubnet", "ipConfigurations": null, "name": "InsideSubnet", "networkSecurityGroup": null, "provisioningState": "Succeeded", "resourceGroup": "CorporateDatacenterResourceGroup", "resourceNavigationLinks": null, "routeTable": { "disableBgpRoutePropagation": null, "etag": null, "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/routeTables/InsideRoutetable", "location": null, "name": null, "provisioningState": null, "resourceGroup": "CorporateDatacenterResourceGroup", "routes": null, "subnets": null, "tags": null, "type": null }, "serviceEndpoints": null } -
Cree otra subred /24 desde el espacio que asignó para la red virtual y asígnela a la tabla de rutas externas.
$ az network vnet subnet create --address-prefix 192.168.2.0/24 --name OutsideSubnet --resource-group CorporateDatacenterResourceGroup --vnet-name CorporateDatacenterVnet --route-table OutsideRoutetable { "addressPrefix": "192.168.2.0/24", "etag": "W/\"874d1019-90a0-44fd-a09c-0aed8f2ede5b\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/virtualNetworks/CorporateDatacenterVnet/subnets/OutsideSubnet", "ipConfigurations": null, "name": "OutsideSubnet", "networkSecurityGroup": null, "provisioningState": "Succeeded", "resourceGroup": "CorporateDatacenterResourceGroup", "resourceNavigationLinks": null, "routeTable": { "disableBgpRoutePropagation": null, "etag": null, "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/routeTables/OutsideRoutetable", "location": null, "name": null, "provisioningState": null, "resourceGroup": "CorporateDatacenterResourceGroup", "routes": null, "subnets": null, "tags": null, "type": null }, "serviceEndpoints": null }
Paso 6. Crear un router CSR1000v.
Cada VM necesita tener 2 interfaces (interna y externa), lo que significa 2 NIC por VM. Cree las 2 NIC y asocie una IP pública a la NIC externa.
- Cree la dirección IP pública.
$ az network public-ip create --name CSRAPublicIP --resource-group CorporateDatacenterResourceGroup --idle-timeout 30 --allocation-method Static { "publicIp": { "dnsSettings": null, "etag": "W/\"38306703-153b-456b-b2e4-xxxxxxxxxxxx\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/publicIPAddresses/CSRA", "idleTimeoutInMinutes": 30, "ipAddress": "40.124.43.82", "ipConfiguration": null, "ipTags": [], "location": "southcentralus", "name": "CSRAPublicIP", "provisioningState": "Succeeded", "publicIpAddressVersion": "IPv4", "publicIpAllocationMethod": "Static", "resourceGroup": "CorporateDatacenterResourceGroup", "resourceGuid": "610e1631-331a-4971-8502-xxxxxxxxxxxx", "sku": { "name": "Basic", "tier": "Regional" }, "tags": null, "type": "Microsoft.Network/publicIPAddresses", "zones": null } } - Cree la NIC externa y asóciele la dirección IP pública.
$ az network nic create --name CSRAOutsideInterface --resource-group CorporateDatacenterResourceGroup --subnet OutsideSubnet --vnet CorporateDatacenterVnet --public-ip-address CSRAPublicIP { "NewNIC": { "dnsSettings": { "appliedDnsServers": [], "dnsServers": [], "internalDnsNameLabel": null, "internalDomainNameSuffix": "plk2sxe5i0l1ccksytfab.jx.internal.cloudapp.net", "internalFqdn": null }, "enableAcceleratedNetworking": false, "enableIpForwarding": false, "etag": "W/\"06fd60de-6547-4992-b506-xxxxxxxxxxxx\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/networkInterfaces/CSRAOutsideInterface", "ipConfigurations": [ { "applicationGatewayBackendAddressPools": null, "applicationSecurityGroups": null, "etag": "W/\"06fd60de-6547-4992-xxxx-xxxxxxxxxxxx\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/networkInterfaces/CSRAOutsideInterface/ipConfigurations/ipconfig1", "loadBalancerBackendAddressPools": null, "loadBalancerInboundNatRules": null, "name": "ipconfig1", "primary": true, "privateIpAddress": "192.168.2.4", "privateIpAddressVersion": "IPv4", "privateIpAllocationMethod": "Dynamic", "provisioningState": "Succeeded", "publicIpAddress": { "dnsSettings": null, "etag": null, "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/publicIPAddresses/CSRAPublicIP", "idleTimeoutInMinutes": null, "ipAddress": null, "ipConfiguration": null, "ipTags": null, "location": null, "name": null, "provisioningState": null, "publicIpAddressVersion": null, "publicIpAllocationMethod": null, "resourceGroup": "CorporateDatacenterResourceGroup", "resourceGuid": null, "sku": null, "tags": null, "type": null, "zones": null }, "resourceGroup": "CorporateDatacenterResourceGroup", "subnet": { "addressPrefix": null, "etag": null, "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/virtualNetworks/CorporateDatacenterVnet/subnets/OutsideSubnet", "ipConfigurations": null, "name": null, "networkSecurityGroup": null, "provisioningState": null, "resourceGroup": "CorporateDatacenterResourceGroup", "resourceNavigationLinks": null, "routeTable": null, "serviceEndpoints": null } } ], "location": "southcentralus", "macAddress": null, "name": "CSRAOutsideInterface", "networkSecurityGroup": null, "primary": null, "provisioningState": "Succeeded", "resourceGroup": "CorporateDatacenterResourceGroup", "resourceGuid": "93413822-e819-4644-ac0d-xxxxxxxxxxxx", "tags": null, "type": "Microsoft.Network/networkInterfaces", "virtualMachine": null } } - Cree la NIC interna.
$ az network nic create --name CSRAInsideInterface --resource-group CorporateDatacenterResourceGroup --subnet InsideSubnet --vnet CorporateDatacenterVnet { "NewNIC": { "dnsSettings": { "appliedDnsServers": [], "dnsServers": [], "internalDnsNameLabel": null, "internalDomainNameSuffix": "gllzkplk2sxe5i0l1ccksytfab.jx.internal.cloudapp.net", "internalFqdn": null }, "enableAcceleratedNetworking": false, "enableIpForwarding": false, "etag": "W/\"bebe539f-b5ff-40fa-a122-5c27951afeb1\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/networkInterfaces/CSRAInsideInterface", "ipConfigurations": [ { "applicationGatewayBackendAddressPools": null, "applicationSecurityGroups": null, "etag": "W/\"bebe539f-b5ff-40fa-a122-5c27951afeb1\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/networkInterfaces/CSRAInsideInterface/ipConfigurations/ipconfig1", "loadBalancerBackendAddressPools": null, "loadBalancerInboundNatRules": null, "name": "ipconfig1", "primary": true, "privateIpAddress": "192.168.1.4", "privateIpAddressVersion": "IPv4", "privateIpAllocationMethod": "Dynamic", "provisioningState": "Succeeded", "publicIpAddress": null, "resourceGroup": "CorporateDatacenterResourceGroup", "subnet": { "addressPrefix": null, "etag": null, "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/virtualNetworks/CorporateDatacenterVnet/subnets/InsideSubnet", "ipConfigurations": null, "name": null, "networkSecurityGroup": null, "provisioningState": null, "resourceGroup": "CorporateDatacenterResourceGroup", "resourceNavigationLinks": null, "routeTable": null, "serviceEndpoints": null } } ], "location": "southcentralus", "macAddress": null, "name": "CSRAInsideInterface", "networkSecurityGroup": null, "primary": null, "provisioningState": "Succeeded", "resourceGroup": "CorporateDatacenterResourceGroup", "resourceGuid": "0f7ae52a-47c3-4563-9fe0-b1484e88296e", "tags": null, "type": "Microsoft.Network/networkInterfaces", "virtualMachine": null } } - Enumera las imágenes CSR1000v disponibles en Azure. Este ejemplo utiliza el nombre urn de cisco:cisco-csr-1000v:16_7:16.7.120171201.
az vm image list --all --publisher Cisco --offer cisco-csr-1000v [ { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "16_5", "urn": "cisco:cisco-csr-1000v:16_5:16.5.120170418", "version": "16.5.120170418" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "16_5", "urn": "cisco:cisco-csr-1000v:16_5:16.5.220171128", "version": "16.5.220171128" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "16_6", "urn": "cisco:cisco-csr-1000v:16_6:16.6.120170804", "version": "16.6.120170804" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "16_6", "urn": "cisco:cisco-csr-1000v:16_6:16.6.220171219", "version": "16.6.220171219" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "16_7", "urn": "cisco:cisco-csr-1000v:16_7:16.7.120171201", "version": "16.7.120171201" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "3_16", "urn": "cisco:cisco-csr-1000v:3_16:3.16.420170208", "version": "3.16.420170208" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "3_16", "urn": "cisco:cisco-csr-1000v:3_16:3.16.520170215", "version": "3.16.520170215" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "csr-azure-byol", "urn": "cisco:cisco-csr-1000v:csr-azure-byol:16.40.120170206", "version": "16.40.120170206" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "csr-azure-byol", "urn": "cisco:cisco-csr-1000v:csr-azure-byol:3.16.0", "version": "3.16.0" }, { "offer": "cisco-csr-1000v", "publisher": "cisco", "sku": "csr-azure-byol", "urn": "cisco:cisco-csr-1000v:csr-azure-byol:3.16.2", "version": "3.16.2" } ] - Implemente el CSR1000v con el nombre urn de la imagen.

Paso 9. Agregue rutas a las tablas de routing y VM.
- Agregue una ruta predeterminada para la subred interna para enrutar el tráfico a través de CSR A estableciendo la dirección IP del siguiente salto como 192.168.1.4. Esto se realiza en InsideRouteTable.
$ az network route-table route create --address-prefix 8.8.8.8/32 --name default_route --next-hop-type VirtualAppliance --resource-group CorporateDatacenterResourceGroup --route-table-name InsideRouteTable --next-hop-ip-address 192.168.1.4 { "addressPrefix": "8.8.8.8/32", "etag": "W/\"ef9e650a-5d70-455d-b958-5a0efc07e7ad\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/routeTables/InsideRouteTable/routes/default_route", "name": "default_route", "nextHopIpAddress": "192.168.1.4", "nextHopType": "VirtualAppliance", "provisioningState": "Succeeded", "resourceGroup": "CorporateDatacenterResourceGroup" } - Agregue una ruta para que el tráfico de la red llegue a Internet en OutsideRouteTable.
$ az network route-table route create --address-prefix 8.8.8.8/32 --name internet --next-hop-type Internet --resource-group CorporateDatacenterResourceGroup --route-table-name OutsideRouteTable { "addressPrefix": "8.8.8.8/32", "etag": "W/\"d2c7e32e-8d32-4856-a3a6-xxxxxxxxxxxx\"", "id": "/subscriptions/09e13fd4-def2-46aa-xxxx-xxxxxxxxxxxx/resourceGroups/CorporateDatacenterResourceGroup/providers/Microsoft.Network/routeTables/OutsideRouteTable/routes/internet", "name": "internet", "nextHopIpAddress": null, "nextHopType": "Internet", "provisioningState": "Succeeded", "resourceGroup": "CorporateDatacenterResourceGroup" } - Inicie sesión en la máquina virtual de Ubuntu y agregue una ruta para forzar el tráfico a través de la interfaz interna a 8.8.8.8. La tabla de rutas de Azure usa automáticamente la primera IP de una subred como su gateway. La subred de la interfaz interna (eth1) es 192.168.1.0/24, lo que significa que 192.168.1.1 es la dirección gw predeterminada para la máquina virtual host.

Troubleshoot
- Habilite los debugs para observar los mensajes durante el failover HA.
CSRA#debug redundancy cloud all CSRA#debug ip http all
- Los errores de autenticación y credenciales se deben a controles de acceso no válidos, que permiten al CSR1000v realizar llamadas de API a la tabla de rutas de Azure. Verifique que las ID correctas estén configuradas en el paso 10.
