The FIB contains mappings between a prefix (identifying a destination network) and its associated Forwarding Equivalence Class (FEC), with the FEC containing one or more resolved Vias defining how traffic should be forwarded towards that destination network.

This feature allows configuring backup entries for static MPLS LFIB routes via EOS SDK RPC to be activated if its corresponding primary entries are unable to forward traffic due to next hops being unresolved or its corresponding interface being down. Any backup entries will not be activated to forward traffic until all primary entries are unviable. Thereby, backup entries configured for the Static MPLS routes are a mechanism to achieve fast failover when the primary path fails.

This feature adds support for Static Route UCMP local forwarding in the multi-agent routing protocol model. Unequal Cost Multi Path (UCMP) for Static Route is a mechanism for forwarding traffic from a device for an ECMP route in the ratio of the weights with which the next hops of that route are programmed in the FIB.

This feature extends link bandwidth extended community deletion mechanism, which previously always required
