Hi all, At this particular site I have 2 1750's. One has an ISDN WIC, the other has WIC-1T.
The serial router has a frame connection, the ISDN router is the backup. Both routers' ethernet interfaces are plugged in to the same hub, not sure of speed or brand. The IP addresses are 172.16.10.10 for the serial router 172.16.10.11 for the ISDN router 172.16.10.12 for the HSRP address. The priority on the serial router is set to 255, and 10 on the isdn router. I have since found that these numbers are not optimal (I am tracking the serial interface), and they will be changed. The problem is (or possibly was) that all of the users and the server at this site had their default gateways incorrectly set to the ip address of the serial router, instead of the HSRP address. This worked fine, except that every 3 days or so, a huge amount of collisions would happen, and the network would stop. To fix it, they unplug the ethernet from the serial router, and plug it back in. I have not had the luxury of a packet sniffer to see exactly what was happening, and since the clients and the server had their DG's changed to the HSRP address, the problem no longer exists. I have another site with the same config (different hub, or may be a switch), same router types and same IOS revisions, and they have never had the problem. The IOS revisions are different on the two routers. Anyone seen this before? I intend to log a call with Cisco, but thought I would ask here first.
