We have a switched network running OSPF with numerous VLANS all funneling out one default gateway for our internet/outside access.
We have had a Comcast cable modem installed to use as a separate internet gateway for Vendors and for out IT departmental testing.
I have set up a port as a router interface off a Layer 3 switch and I want to route all traffic from a specific VLAN on our campus out that interface, however, that VLAN and the routed interface is picked up by OSPF and included in the routing table. I've tried to use a route-map and tell that subnet to go out the routed interface and use the comcast device IP as it's gateway, but it's still routing the traffic internally. I'm stumped. How do I specify a separate default gateway and route for that specific traffic?
