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 Enter the time interval for sending and receiving BFD control packets from 100 to 1000. Changing IPv4 static route session parameters Configure BFD sessions with default intervals and a default role. Configure the following for all static routes: • Desired TX Interval • Required Min RX Interval • Detection Multiplier • system role These parameters are configured for all static routes. If you change a parameter, the change affects all sessions for static routes. To change parameters for static route sessions, use the following command. • Change the parameters for all static route sessions in CONFIGURATION mode. ip route bfd interval milliseconds min_rx milliseconds multiplier value role [active | passive] Enter the time interval for sending and receiving BFD control packets; from 100 to 1000. NOTE: By default, OSPF uses the following BFD parameters for its neighbors: min_tx = 200 msec, min_rx = 200 msec, multiplier = 3, role = active. Disabling BFD for IPv4 Static Routes If you disable BFD, all static route BFD sessions are torn down. A final 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 CONFIGURATION Mode Establishing BFD Sessions for IPv6 Static Routes To establish a BFD session for IPv6 static routes, use the following command. Establish BFD sessions for all neighbors that are the next hop of a static route. ipv6 route bfd [interval interval min_rx min_rx multiplier value role {active | passive}] CONFIGURATION Mode Enter the time interval for sending and receiving BFD control packets from 100 to 1000. 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 configured in milliseconds Establishing BFD Sessions for IPv6 Static Routes in a non-default VRF instance To establish a BFD session for IPv6 static routes in a non-default VRF instance, use the following command.
