ipv6 route bfd [prefix-list prefix-list-name] [interval interval min_rx min_rx multiplier
value role {active | passive}]
Example of the show bfd neighbors Command to Verify Static Routes
To verify that sessions have been created for static routes, use the show bfd neighbors command.
R1(conf)#ipv6 route 11::1 11::2
R1(conf)#ipv6 route bfd
R1(conf)#do show bfd neighbors
* - Active session role
Ad Dn - Admin Down
B - BGP
C - CLI
I - ISIS
O - OSPF
O3 - OSPFv3
R - Static Route (RTM)
M - MPLS
V - VRRP
VT - Vxlan Tunnel

To view detailed session information, use the show bfd neighbors detail command, as shown in the examples in Displaying BFD
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 Conguration and Verication
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.
Dell(conf)#do show bfd neighbors
