We have 2 routers plugged into the same Vlan on a cat 5500. All layer 2 info seems to be showing up just fine from all devices. The routers have a basic simple config. You know e0 ip addrees/subnet... several people have looked at it and agree all the configs look just fine. Here is what happens When we ping from one particular router (called it sneezy) to the other (dopey), there is no response. Debug ip packet revelas that sneezy is getting encapsulation failed. (This happens on any other router plugged into that port on the switch so it is not router specific, and they are all using the same ethernet encaps arpa). Also, the arp packets from sneezy seemed to be going out as 0000.0000.0000 instead of ffff.ffff.ffff.ffff I am going to simply assume a hardware malfunction on that port of the switch unless someone here has seen a similiar issue and can attribute it to something else???? _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
