bfd echo-src-ip-address


bfd echo-src-ip-address <IPV4-ADDR>

no bfd echo-src-ip-address


Sets the source IPv4 address for BFD echo packets. This address is used in all echo sessions.


The source IP address must not be on the same network segment as any switch interface, otherwise a large number of ICMP redirect packets may be sent by the remote device, causing network congestion.

The no form of this command removes the source IPv4 address for BFD echo packets, which causes the switch to stop sending echo packets. When a valid value is set, all sessions with a peer that is capable of receiving echo packets, will start transmitting echo packets. BFD control sessions continue to run concurrently with echo packets.
