Step 1

From the main menu, choose Administration > Manage Provider Access > .

Step 2

Enter the following values for the SR-PCE provider fields:

1. Required fields:

   • Provider Name: Name of the SR-PCE provider.

   • Credential Profile: Select the previously created Cisco SR-PCE credential profile.

   • Family: Select SR_PCE. All other options should be ignored.

   • Protocol:

     • Select HTTP and enter required fields. HTTP is required to process RSVP, TreeSID and PCEP sessions. The default port is 8080.

     • Select GRPC or GRPC_SECURE (gRPC with Transport Layer Security (TLS)) and enter required fields. These settings are required to process topology, SR-MPLS, and SRv6 policies. Only one of these options can be used. If GRPC_SECURE is selected, you must provide the trusted certificate in the Certificate profile field

   • Provider Properties: Enter property keys and values:

     Property Key	Value
     auto-onboard	off Note   Use this option if you plan to manually (via UI or CSV import) enter all of your network devices. When devices are discovered, the device data is recorded in the Cisco SR-PCE database, but is not registered in Crosswork Network Controller Inventory Management database.
     	unmanaged If this option is enabled, all devices that Crosswork Network Controller discovers will be registered in the Crosswork Network Controller Inventory Management database, with their configured state set to unmanaged. SNMP polling will be disabled for these devices, and no management IP information will be included. To get these devices into the managed state later, you will need to either edit them via the UI or export them to a CSV make modifications and then import the updated CSV. You can also assign credential profiles by adding them to the device CSV file before import (the credential profiles must already exist).
     	managed If this option is enabled, all devices that Cisco SR-PCE discovers will be registered in the Crosswork Network Controller Inventory Management database, with their configured state set to managed. Typically suitable for an environment that has same device profiles, devices are managed by their TE router-ID, and all devices can be discovered by the Cisco SR-PCE. SNMP polling will be enabled for these devices, and Cisco SR-PCE will also report the management IP address (TE Router ID for IPv4, or IPv6 Router ID for IPv6 deployment). The devices will be added with the credential profile associated with the device-profile key in the SR-PCE provider configuration. If you enable this option for IPv6 deployment, devices will still register as unmanaged in the inventory. When you delete an onboarded device that was added via SR-PCE discovery with auto-onboard set to managed, the topology service adds it again as unmanaged. This ensures that devices that have been removed are not automatically managed again unless they acquire a new TE-ID. To manage a rediscovered device, update its status manually.
     device-profile	The name of a credential profile that contains SNMP credentials for all the new devices. Note   This field is necessary only if auto-onboard is set to managed or unmanaged. If the auto-onboard is set to managed and there is no valid device-profile set, the device will instead be onboarded as unmanaged.
     outgoing-interface	eth1 Note   You have to set this only if you want to enable Cisco Crosswork application access to SR-PCE via the data network interface when using the two NIC configuration.
     preferred-stack	ipv4 or ipv6 or NOT SET. This property is applicable only for dual stack deployments.
     topology	off or on. This is an optional property. If not specified, the default value is on. If value is specified as off, it means that L3 topology is not accessible for the SR-PCE provider.
     pce	off or on. This is an optional property. If not specified, the default value is on. If value is specified as off, it means that LSPs and policies are not accessible for the SR-PCE provider.

     Note

     Topology can be visualized even with auto-onboard as off and a device-profile is not specified. If managed or unmanaged options are set and you want to delete a device later, you must either:. Reconfigure and remove the devices from the network before deleting the device from Crosswork Network Controller. This avoids Crosswork Network Controller from rediscovering and adding the device back. Set auto-onboard to off, and then delete the device from Crosswork Network Controller. However, doing so will not allow Crosswork Network Controller to detect or auto-onboard any new devices in the network. It is not recommended to modify auto-onboard options once set. If you need to modify them: Delete the provider and wait until deletion confirmation is displayed in the Events window. Re-add the provider with the updated auto-onboard option. Confirm the provider has been added with the correct auto-onboard option in the Events window.

2. Optional values:

   • Timeout: The amount of time (in seconds) to wait before timing out the connection to the SR-PCE server. The default is 30 seconds.

Step 3

Click Save to add the SR-PCE provider.

Step 4

Confirm that the SR-PCE provider shows a green Reachability status without any errors. You can also view the Events window (Administration > Events) to see if the provider has been configured correctly.

Step 5

Repeat this process for each SR-PCE provider.
