3 Congure BFD for static route using the ip route bfd command
Establishing BFD Sessions for IPv4 Static Routes
Sessions are established for all neighbors that are the next hop of a static route.
To establish a BFD session, use the following command.
Establish BFD sessions for all neighbors that are the next hop of a static route.
ip route bfd [interval interval min_rx min_rx multiplier value role {active | passive}]
CONFIGURATION Mode
Establishing BFD Sessions for IPv4 Static Routes in a non-default VRF
instance
To establish a BFD session for IPv4 static routes in a non-default VRF instance, use the following command.
Establish BFD sessions for all neighbors that are the next hop of a static route.
ip route bfd [vrf vrf-name] [interval interval min_rx min_rx multiplier value role {active |
passive}]
CONFIGURATION Mode
Changing IPv4 Static Route Session Parameters
BFD sessions are congured with default intervals and a default role.
The parameters you can congure are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role. These
parameters are congured for all static routes. If you change a parameter, the change aects all sessions for static routes. To change
parameters for static route sessions, use the following command.
Change parameters for all static route sessions.
ip route bfd interval milliseconds min_rx milliseconds multiplier value role [active |
passive]
CONFIGURATION Mode
NOTE
: By default, OSPF uses the following BFD parameters for it's neighbors: min_tx = 200 msec, min_rx = 200 msec,
multiplier = 3, role = active. The values are congured in milliseconds
Disabling BFD for IPv4 Static Routes
If you disable BFD, all static route BFD sessions are torn down.
A nal Admin Down packet is sent to all neighbors on the remote systems, and those neighbors change to the Down state. To disable BFD
for IPv4 static routes, use the following command.
Disable BFD for static routes.
no ip route bfd
