bfd echo-src-ip-address


Not supported on the 8320 and 8325.


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

no bfd echo-src-ip-address <IPV4-ADDR>


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


The source IP address must not be one the same network segment as any interface on the switch, 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 source IPv4 address for BFD echo packets, which causes the switch to stop sending echo packets. When a valid value is set, all established or new 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.

Command context
