Command Reference, Cisco IOS XE Denali 16.3.x (Catalyst 3650 Switches)

border

border ip address

Syntax Description


`ip address`	Configures the IP address of the fabric border device.

Command Default

None.

Command Modes

Fabric-auto-domain configuration

Command History


Release	Modification
Cisco IOS XE Denali 16.3.1	This command was introduced.

Usage Guidelines

Use this command to configure the IP address of the fabric border device. Border devices in the fabric domain connect traditional Layer 3 networks or different fabric domains to the local domain, and translate reachability and policy (VRF and SGT ) information from one domain to another. Fabric border devices correspond to proxy egress tunnel routers in LISP.

This command auto-generates LISP configuration, to orchestrate the fabric overlay. The show-running configuration command shows the fabric domain configuration including the auto-generated commands.

Examples

The following configuration is auto-generated when this command is run on your device:

Device(config-fabric-auto-domain)#border 198.51.100.4


    ipv4 use-petr 198.51.100.4 priority 10 weight 10

For information about the ipv4 proxy etr command, see LISP Command Reference..

context

context name name id id

Syntax Description


context name	Creates a new layer 3 context in the fabric domain.
id `id`	Assigns an ID to the context.

Command Default

None

Command Modes

Fabric-auto-domain configuration mode

Command History


Release	Modification
Cisco IOS XE Denali 16.3.1	This command was introduced.

Usage Guidelines

A virtual context provides virtualization at the device level, using virtual routing and forwarding (VRF), to create multiple instances of Layer 3 routing tables. Contexts or VRFs provide segmentation across IP addresses, allowing for overlapped address space and traffic separation. \

This command enables the auto-generation of LISP (Locator ID Separation Protocol) and VRF (Virtual Routing and Forwarding) configuration, to orchestrate the fabric overlay. The show-running configuration command shows the virtual context configuration including the auto-generated base line commands.

Examples

Device(config-fabric-auto-domain)#context name guest
id 10

The following configuration is auto-generated when this command is run on your device:

ip vrf  guest
    description Auto-provisioned vrf  for context example-context (source – fabric auto)
router lisp
     eid-table vrf  guest instance-id 10

control-plane

control-plane { ip address| auth-keykey}

Syntax Description


`ip address`	Configures the IP address of the control-plane device.
auth-key `key`	Configures the key to authenticate access to the control-plane device.

Command Default

None

Command Modes

Fabric-auto-domain configuration mode

Command History


Release	Modification
Cisco IOS XE Denali 16.3.1	This command was introduced.

Usage Guidelines

Use the command to configure the control-plane device IP address and the authentication key, to allow fabric edge devices to communicate with the control-plane device.

This command auto-generates LISP configuration, to orchestrate the fabric overlay. The show-running configuration command shows the fabric domain configuration including the auto-generated commands.

Examples

The following configuration is auto-generated when this command is run on your device:

Device(config-fabric-auto-domain)#control-plane 2.2.2.2
auth_key examplekey123

router lisp 
locator-set default.RLOC
ipv4-interface Loopback0 priority 10 weight 10
exit

ipv4 etr map-server 2.2.2.2 key examplekey123
ipv4 etr

For information about theipv4 map-server and ipv4 map-resolver commands, see LISP Command Reference..

domain

Configures the fabric domain and enters fabric-auto-domain configuration mode. The no version of this command deletes the fabric domain.

domain { default| name name}

no domain

Syntax Description


default	Configures the default fabric domain and enters fabric-auto domain configuration mode.
name `name`	Configures a new fabric domain and enters fabric-auto domain configuration mode.

Command Default

None

Command Modes

Fabric-auto configuration mode

Command History


Release	Modification
Cisco IOS XE Denali 16.3.1	This command was introduced.

Usage Guidelines

We recommend that you use the default domain, unless your network requires you to create a new domain. This command allows you to enter fabric-auto domain configuration mode where you can configure edge, control-plane and border devices in the fabric domain.

Examples

Device(config-fabric-auto)#domain default

Device(config-fabric-auto)#domain name exampledomain

debug fabric auto

debug fabric auto {trace | level | {error | verbose}}

Syntax Description


trace	Enables the tracing for the commands auto-generated when the fabric-auto command is executed.
level error	Displays the errors encountered during Fabric Overlay provisioning.
level verbose	Displays the maximum number of messages encountered during Fabric Overlay provisioning.

Command Default

None.

Command Modes

Privileged Exec

Command History


Release	Modification
Cisco IOS XE Denali 16.3.1	This command was introduced.

Usage Guidelines

Use these debug commands to troubleshoot your fabric domain configuration, and trace the commands auto-generated by the fabric auto command, and display the errors encountered.

The no debug fabric auto level verbose command disables the display of all the messages encountered during fabric provisioning.

fabric auto

To enable automatic fabric provisioning and enter automatic fabric configuration mode, use the fabric auto command in global configuration mode.

fabric auto

Syntax Description


fabric auto	Enables automatic fabric provisioning and enters fabric-auto configuration mode.

Command Default

None

Command Modes

Global configuration

Command History


Release	Modification
Cisco IOS XE Denali 16.3.1	This command was introduced.

Usage Guidelines

The fabric auto command allows you to configure all the elements in your fabric domain automatically. Additionally, this command enables the auto-generation LISP, VLAN, VRF configuration, to orchestrate the fabric overlay. The show-running configuration command shows the fabric domain configuration including the and auto-generated base line commands.

Examples

Device(config)#fabric auto

host-pool name

Creates an IP pool to group endpoints in the fabric domain, and enters host-pool configuration mode.

host-pool name name{vlan ID| gateway ipv4 -address/subnet mask|context name name|use-dhcp ip4 address}

Syntax Description


vlan `ID`	Configures a VLAN ID to associate with the host-pool.
context name `name`	Associates a context or a VRF with the host-pool.
gateway `ipv4 address/subnet mask`	Configures the routing gateway IP address and subnet mask for the host-pool.
use-dhcp `ipv4 address`	Configures a DHCP server for the host-pool.

Command Default

None

Command Modes

Command History


Release	Modification
Cisco IOS XE Denali 16.3.1	This command was introduced.

Usage Guidelines

Use the host-pool command to group endpoints in the fabric domain into IP pools, and identify them with a VLAN ID and an IP subnet.

This command auto-generates LISP configuration, to orchestrate the fabric overlay. The show-running configuration command shows the fabric domain configuration including the auto-generated commands.

Examples

This example configures a host-pool in your fabric domain.

device(config-fabric-auto-domain)#host-pool name VOICE_DOMAIN
