| How do keepalives work? Does the router send messages that "echo" back to itself? | |

| I believe a keepalive is more for the other router than for itself. For example, router a sends a keepalive that router b hears. Router b now know that router a is still there and keeps any routing table entries that go through router a in its table. Hope that helps. | |

| That would be tied into part of LMI? | |

| Thanks for the replies!
The Cisco link does not seem to work.
I did, however, come accross the following link: http://www.cisco.com/univercd/cc/td...twk/ita/k12.htm
It gave the following explanation, which is sufficient for now:

keepalive message: Message sent by one network device to inform another network device that the virtual circuit between the two is still active
