Configuring a non-DvR BEB to join the DvR backbone

About this task

Configure a non-DvR backbone edge bridge (BEB) to join the DvR backbone so that it can receive redistributed DvR host routes from all DvR Controllers in the SPB network.

Note

Note

On a non-DVR BEB, the redistributed host routes from the DvR backbone are not automatically installed in the IP routing table. To utilize the backbone host routes to optimize traffic forwarding (forwarding in the data plane), you must explicitly configure an IS-IS accept policy with a backbone route policy using the command accept backbone-route-map <route-map-name>, and specifying a suitable route-map to select the list or range of DvR backbone host routes to be installed in the routing table.

For more information on configuring an IS-IS accept policy with a backbone route policy, see Configuring IS-IS Accept Policies.

Procedure

  1. Enter IS-IS Router Configuration mode:

    enable

    configure terminal

    router isis

  2. Configure a non-DvR BEB to join the DvR backbone.

    [no]|[default] backbone enable

  3. Verify the configuration using the following commands.
    • show dvr backbone-members

    • show dvr backbone-members non-dvr-beb

    • show dvr backbone-entries

    • show isis

Example

Switch3:1>enable
Switch3:1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch3:1(config)#router isis
Switch3:1(config-isis)#show dvr

Configure the non-DvR BEB to join the DvR backbone.

Switch3:1(config-isis)#backbone enable

Verify the configuration. View the DvR backbone members.
