for BGP Information.
Establishing Sessions for IPv6 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 IPv6 neighbors that are the next hop of a static route.
CONFIGURATION mode
ipv6 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#show run | grep bfd
bfd enable
ipv6 route bfd prefix-list p6_le
ipv6 route bfd vrf vrf1
ipv6 route bfd vrf vrf2
ipv6 route bfd vrf vrf1 prefix-list p6_le
The following example shows that sessions are created for static routes for the default VRF.
