Configuring BFD for static routes single hop by using IPv4 addressing

Consider a scenario in which you have two systems, R1 and R2. R1 and R2 share a static route session, as illustrated in the reference network diagram. The following list provides the addresses of R1 and R2.
  • R1 loopback address—1.1.1.1/32
  • R1 interface address—10.10.10.1/24
  • R2 loopback address—2.2.2.2/32
  • R2 interface address—10.10.10.2/24
Figure 1. Configuring BFD for static routes single hop by using IPv4 addressing

To configure a BFD session between R1 and R2, perform the following steps in configuration mode.

Table 1. Configuring BFD for Static Routes Single Hop by Using IPv4 Addressing
Router Step Command
R1 Create a BFD template called test. See section Configuring the BFD template.
R1 Associate the BFD test template with the destination address of R2 and the source address of R1.
Note: Configuring session template is mandatory.
vyatta@R1# set protocols bfd destination 10.10.10.2 source 10.10.10.1 template test
R1 Register R2 as a BFD neighbor.
vyatta@R1# set protocols static route 2.2.2.2/32 next-hop 10.10.10.2 fall-over bfd
R1 Commit the configuration.
vyatta@R1# commit
R1 Save the configuration.

R2 Create a BFD template called test. See section Configuring the BFD template.
R2 Associate the BFD test template with the destination address of R1 and the source address of R2.
