You can only enable BFD for VRRP in INTERFACE command mode (vrrp bfd
all-neighbors
).

BGP peer group.
ip route bfd
Enable BFD for all neighbors configured through static routes.
Syntax
ip route bfd [interval interval min_rx min_rx multiplier value
role {active | passive}]
To disable BFD for all neighbors configured through static routes, use the no ip
route bfd [interval interval min_rx min_rx multiplier value
role {active | passive}] command.
Parameters
interval
milliseconds
(OPTIONAL) Enter the keywords interval to specify non-
default BFD session parameters beginning with the
transmission interval. The range is from 50 to 1000. The
default is 200.
min_rx
milliseconds
Enter the keywords min_rx to specify the minimum rate at
which the local system receives control packets from the
remote system. The range is from 50 to 1000. The default is
