I have a cisco router 881, this is the platform and version C880DATA-UNIVERSALK9-M, Version 15.0(1)M4. My problem is that anytime the WAN interface on this router goes down, either due to a power failure or the cable that connect to the interface is disconnected, you have to manually go into the router wan interface configuration mode and issue the no keepalive command before the interface is brought up back. Is anyone here can explain why this is happening and how I can go about it? Is there anyway to automate the no keepalive command so that the command is issue periodically after a period of time or when an event such as the interface status change state to down. Thank you.
