View Remote Unicast FIB
In SPBM, the IS-IS link-state database carries the B-MAC addresses. To do this, SPBM supports an IS-IS TLV that advertises the I-SID and B-MAC information across the network. Each node has a System ID, which also serves as Backbone MAC address (B-MAC) of the switch. These Backbone MAC addresses are populated 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.
