Configuring BFD <strong>for</strong> Port-Channels<br />

BFD on port-channels is analogous to BFD on physical ports. If no routing protocol is enabled, and a<br />

remote system fails, <strong>the</strong> local system does not remove <strong>the</strong> connected route until <strong>the</strong> first failed attempt to<br />

send a packet. If BFD is enabled, <strong>the</strong> local system removes <strong>the</strong> route when it stops receiving periodic<br />

control packets from <strong>the</strong> remote system.<br />

There is one BFD Agent <strong>for</strong> VLANs and port-channels, which resides on RP2 as opposed to <strong>the</strong> o<strong>the</strong>r<br />

agents which are on <strong>the</strong> line card. There<strong>for</strong>e, <strong>the</strong> 100 total possible sessions that this agent can maintain is<br />

shared <strong>for</strong> VLANs and port-channels.<br />

Configuring BFD <strong>for</strong> port-channels is a two-step process:<br />

1. Enable BFD globally on all participating routers. See Enabling BFD globally on page 604.<br />

2. Enable BFD at interface level at both ends of <strong>the</strong> port-channel. See page 622.<br />

To establish a session, BFD must be enabled at interface level on both ends of <strong>the</strong> link, as shown in<br />

Figure 423. The session parameters do not need to match.<br />
