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
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.
