I have a layer 3 switch with two routers connected to it. When I trace from one WAN site to another through this switch I hit vlan 31 and just stop. I can get on the switch and trace to the 10.175.0.0/24 network but from our other WAN connection I can't get past it. If I source the IP of vlan 31 on that same switch I cannot get to the 10.175.0.0/24 network. I have a static route for the 10.175.x.x net on the switch pointing to the router that is connected via an access port. The router's gi0/1 interface has 10.10.1.250 address which is a part of the vlan 710 on the layer3 switch. Any ideas why I can't route past that 10.210.31.3 address?
