Establishing Sessions for Static Routes for Default VRF
Sessions are established for all neighbors that are the next hop of a static route on the default VRF.
Figure 12. Establishing Sessions for Static Routes
To establish a BFD session, use the following command.
• Establish BFD sessions for all neighbors that are the next hop of a static route.
CONFIGURATION mode
ip route bfd [prefix-list prefix-list-name] [interval interval min_rx min_rx multiplier value
role {active | passive}]
To verify that sessions have been created for static routes, use the show bfd neighbors command.
R1(conf)#ip route 2.2.3.0/24 2.2.2.2
R1(conf)#ip route bfd
R1(conf)#do show bfd neighbors
* - Active session role
Ad Dn - Admin Down

To view detailed session information, use the show bfd neighbors detail command.
Establishing Sessions for Static Routes for Nondefault VRF
You can also create nondefault VRFs and establish sessions for all neighbors that are the next hop of a static route.
To establish a BFD session for nondefault VRFs, use the following command.
• Establish BFD sessions for all neighbors that are the next hop of a static route.
CONFIGURATION mode
ip route bfd vrf vrf-name [prefix-list prefix-list-name] [interval interval min_rx min_rx
multiplier value role {active | passive}]
Example Configuration and Verification
The following example contains static routes for both default and nondefault VRFs.
Dell#sh run | grep bfd
bfd enable
ip route bfd prefix-list p4_le
ip route bfd vrf vrf1
