Dell Force10 S4810P - Configuring Bfd

150 | Bidirectional Forwarding Detection (BFD)

Configuring BFD for static routes is a three-step process:
1. Enabling BFD globally.
2. On the local system, establish a session with the next hop of a static route. Refer to Configuring BFD
for Static Routes.
3. On the remote system, establish a session with the physical port that is the origin of the static route.
Refer to Establishing a session on physical ports.

Establishing sessions for static routes
Sessions are established for all neighbors that are the next hop of a static route.
To establish a BFD session:
Verify that sessions have been created for static routes using the command
show bfd neighbors, as shown
in the example below.
R1(conf)#ip route 2.2.3.0/24 2.2.2.2
R1(conf)#ip route bfd
R1(conf)#do show bfd neighbors
