Hi!
I have a very strange problem with 2 cisco routers connected over layer 2 cisco switches (catalyst 6500). Both routers are connected over a VLAN and they see each others IP- and MAC-address in the arp cache (they can ping each other). But when I traceroute from one to the other, I see a an additional hop
- * * before I see the ip-address of the other end (this happens on both routers). Also when I mirror the switchports where the routers are connected, I only see traceroute udp packets with TTL=2. I do not see the TTL=1 packets, because of this strange internal hop. This causes big problems with HSRP, because HSRP has TTL=1. And this first hop is this internal hop, so HSRP packets never come to the switch (and not to the other router).
Any ideas?
Thanks.
