Description
Using the mfr timer hello command, you can set the interval for a frame relay
bundle link to send hello message. Using the undo mfr timer hello command, you
can restore the default setting.
Both ends of a frame relay bundle link periodically send hello message to the peer
end. After the peer receives the hello message, it will response hello
acknowledgement message.
