I've got a remote site. The remote site has a 2800 series router and it's connected to a L2 switch.
Serial WIC: 184.108.40.206
The default-gateway on the switch is set to 10.126.5.1.
I can ping across the wan to a host connected to the switch on the 10.126.5.0 subnet and the 10.125.5.0 subnet.
While running wireshark, I get two replies from each ping to the 10.125.5.0 subnet ONLY.
Pinging 10.126.5.0 host will result in:
Pinging a host on the 10.125.5.0 subnet results in:
Has anyone seen this? I'm "assuming" that it's because the router is receiving the packet on the secondary address and could be sending a reply from both addresses, but that's still really odd. My pings don't timeout, traces don't timeout, but I still get the double replies. My traces look right too. There are no "extra" hops per se.
