2 Enable BFD for specific BGP neighbors using the
command or for all BGP
command. For example:
-> ip bgp bfd-std all-neighbors
-> ip bgp neighbor neigh1 bfd-std enable
Configuring BFD Support for VRRP Track Policies
1 Register VRRP with the BFD protocol using the
command. For example:
-> vrrp bfd-std enable
2 Enable BFD for a specific track policy using the
command. For example:
-> vrrp track 2 address 10.1.1.1 bfd-std enable
Make sure that the track policy is associated with at least one of the virtual routers. In addition, note that
the value of the address parameter should be a remote interface address. BFD cannot be configured for a
local interface address.

Note. To display the VRRP tracking policies on which BFD is enabled, use the
command.

Configuring BFD Support for Static Routes
Enable BFD support for a specific static route using the
command or for
all static routes using the
command. For example:
-> ip static-route 10.1.1.1 255.0.0.0 gateway 10.1.1.25 bfd status enable
-> ip static-route all bfd-std enable
To create a BFD session for a static route, make sure the gateway address does not match any of the local
interface addresses on the switch and that BFD is enabled on the interface on which the gateway address
exists. If multiple routes are configured with the same gateway address, only one BFD session will run.
interface addresses on the switch and that BFD is enabled on the interface on which the gateway address
exists. If multiple routes are configured with the same gateway address, only one BFD session will run.
Note. To display the static routes on which BFD is enabled use the
command. An asterisk
appears before the gateway address of a BFD enabled static route. For example:
-> show ip route
+ = Equal cost multipath routes
* = BFD Enabled
