View Remote IPv6 Unicast FIB
In SPBM, each node has a System ID, which also serves as Backbone MAC address (B-MAC) of the switch. The system populates these Backbone MAC addresses into the SPBM VLAN Forwarding Information Base (FIB). When the system discovers a network topology and stores it in the IS-IS link-state database, each node calculates shortest path trees for each source node, so that a unicast path now exists from every node to every other node. With this information, each node populates unicast information that it receives from SPBM into the FIB for forwarding purposes.
I-SIDs are only used for virtual services (Layer 2 VSNs and Layer 3 VSNs). If you only enable IP Shortcuts on the Backbone Edge Bridges, I-SIDs are not exchanged in the network as IP Shortcuts allows for Global Routing Table (GRT) IP networks to be transported across IS-IS.
About this task
Perform this procedure to display the remote IPv6 unicast FIB. You can view the IPv6 routes from remote Backbone Edge Bridges (BEBs).
Procedure
- In the navigation pane, expand the folders.
- Select SPBM Remote.
- Select the IPv6 Unicast FIB tab.
- Optional: Select the Filter button to filter the rows on basis of specific criteria.
