interval min_rx min_rx multiplier value role {active | passive}]
To disable BFD for all IPv6 neighbors configured through static routes, use the no ipv6 route bfd
[vrf vrf-name] [prefix-list prefix-list-name] [interval interval min_rx
min_rx multiplier value role {active | passive}] command.
Parameters
vrf vrf-name (Optional) Enter the keyword vrf and then the name of the VRF to enable or
disable BFD on the next-hop IPv6 neighbor corresponding to that VRF.
prefix-list prefix-
list-name
(Optional) Enter the keyword prefix-list followed by the name of the prefix

interval
milliseconds
(OPTIONAL) Enter the keywords interval to specify non-default BFD session

The default is 200.
min_rx

The default is 200.
multiplier value Enter the keywords multiplier to specify the number of packets that must be
