Routing Protocol Peering
In a redundant supervisor engine and dual MSFC configuration, one supervisor engine is fully
operational (active) and the other supervisor engine is in standby mode; however, both MSFCs are
operational (in terms of programming the PFC on the active supervisor engine) and act as independent
routers.
PFC: With the PFC, MLS entries can be associated with either MSFC (based on which MSFC routed

the first packet). Only the PFC on the active supervisor engine switches the packets.
PFC2: With PFC2, only the designated MSFC programs the forwarding information base (FIB) the

adjacency table, Cisco IOS software, and policy routing ACLs on the active supervisor engine. If you
configure static routes or policy routing, you must have the identical configuration on both MSFCs.
If you have a static route on the nondesignated MSFC that is not on the designated MSFC, that route
will not be programmed in the PFC2.
