Enables or disables Bidirectional Forwarding Detection (BFD) protection of BGP peering sessions.
| all | Specifies that the configuration applies to all neighbors in the specified address family. If no address family is specified or if an IPv4 address is specified, the configuration applies to all IPv4 neighbors. If an IPv6 address family is specified, the configuration applies to all IPv6 neighbors. |
| remoteaddr | Specifies the IPv4 or IPv6 address of a BGP neighbor. The switch uses the IP address format to determine if the address is an IPv4 or IPv6 address. |
| bfd on | off | Configures BFD detection for the specified neighbor(s). |
BFD is disabled on neighbor by default.
You must disable a neighbor before configuring BFD.
The following example enables BFD on neighbor 192.168.24.2:
# disable bgp neighbor 192.168.24.2 # configure bgp neighbor 192.168.24.2 bfd on # enable bgp neighbor 192.168.24.2
