Configuration Example: BFD for IP Static Routes Single-Hop Session
The following figure shows a single-hop
static BFD session. BFD can monitor the next hop.
The following configuration example configures a single-hop static BFD session as illustrated in the preceding figure. Router 1 has a static route to 10.20.20.20/24 with the next hop as 10.0.0.2/24. Router 2 has a static route to 10.10.10.10/24 with the next hop as 10.0.0.1/24. BFD session parameters are also configured, and the holdover timer is set.
