Configuration Examples for Multihop BFD

This section provides the configuration example for multihop BFD.

Example : Configuring Multihop BFD

The following example shows how to configure BFD in a BGP network. In the following example, the simple BGP network consists of Router A and Router B. Fast Ethernet interface 0/1 on Router A is connected to the same network as Fast Ethernet interface 6/0 in Router B.
