Configure BFD for Port-Channels
BFD on port-channels is analogous to BFD on physical ports.
If you enable the no routing protocol, and a remote system fails, the local system does not remove the
connected route until the first failed attempt to send a packet. If you enable BFD, the local system removes
the route when it stops receiving periodic control packets from the remote system.
There is one BFD agent for VLANs and port-channels that resides on RP2, as opposed to the other agents that
are on the line card. Therefore, the 100 total possible sessions that this agent can maintain is shared for
VLANs and port-channels.
Configuring BFD for port-channels is a two-step process:
• Enable BFD globally. Refer to Enabling BFD Globally.
• Establish sessions on port-channels. Refer to Establish Sessions on Port-Channels.
