Unix workstations and HSRP virtual as default gateway?
Got an odd situation, I'm hoping someone with some unix / linux experience can weigh in here.
I have a topology with 2 Layer 3 3560s acting as my HSRP routers. Each 3560 has a HSRP instance running on a physical (non - SVI) interface. These interfaces are connected into a Layer 2 switch, as is the Linux server. The physical interfaces are .2 and .3, the hsrp virtual is .1
When I point the linux default GW to .1, I can not access the network. When I point it to .2 or .3, all is well. All my other non-linux hosts are just fine. We have disabled the firewall and security svcs on the linux server and it still does not work when pointed to the .1 gateway. Any thoughts?

Thanks to both of you for the helpful advice, in the end it was this and Wireshark that helped me nail this down.
For some reason the client has a Ricoh printing appliance that was RIP advertising itself as the .1 default gateway. Once we determined the default gateway mac address in the unix arp table was wrong, we used wireshark to track down the offender.
