Configuring BFD Configuring BFD

-> ip bgp bfd-state all-neighbors disable
To display the BFD status of BGP neighbors, use the show ip bgp neighbors command. For example:
-> show ip bgp neighbors
Legends: Nbr = Neighbor
As = Autonomous System
Nbr address As Admin state Oper state BGP Id Up/Down BFD Status
---------------+-----+-----------+------------+-----------+------------+---------
100.1.1.10 2 enabled established 3.3.3.3 00h:02m:19s enabled
Use the show ip bfd sessions command to view BFD sessions with all BFD neighbors. For example:
-> show ip bfd sessions
Legends: Neg. = Negotiated
Discr = Discriminator
Intvl = Interval (in milliseconds)
Local Interface Neighbor State Remote Neg. Rx Neg. Tx EchoRx
Discr Name Address Discr Intvl Intvl Intvl
------+-----------+--------------+----------+------+----------+--------+-------
1 v1001 101.1.1.11 UP 1 300 300 300
2 v2000 200.1.1.1 UP 0 0 0 300
-> show ip bfd sessions 1
Local discriminator = 1,
Neighbor IP Address = 100.1.1.10,
Requested Session Type = ASYNC ,
Interface IfIndex = 2,
Source UDP Port = 49152,
State = UP,
Session Operating Mode = None,
Remote discriminator = 1,
Negotiated Tx interval = 300,
Negotiated Rx interval = 300,
Echo Rx interval = 300,
Multiplier = 3,
Applications Registered: = BGP
Configuring BFD Support for VRRP Tracking
The steps below show you how to configure and verify BFD support for VRRP protocol, so that VRRP is
a registered protocol with BFD and receives forwarding path detection failure messages from BFD.
1 To associate VRRP protocol with BFD liveliness detection, register VRRP with BFD at the protocol
level using the vrrp bfd-state command as shown below:
-> vrrp bfd-state enable
Note. VRRP protocol supports BFD in the echo-only operational mode.
