I have 3 sites A, B, and C. Each has a 3512G switch at the core and 3 2950s that tie back to the 3512 via fiber. Sites A and B need to connect to C via fiber. Each site is going to be on a different subnet so I need to enable routing between them. On the 3512's at both A and B, I know I can use one gigabitethernet port as a layer 3 port, give it an IP address and give each 3512 a route to the IP of the gigethernet port at site C that they are connected to. On the 3512 at the central site (site C) what route statements do I need? I know I need one to route to the subnet in site A, one to route to the subnet in site B, but what do I need to allow traffic destined for site C to go out to the 2950's that are connected to 3 of the 10 GBIC ports. These 3 ports are layer 2 ports, part of VLAN1 (the only VLAN). Is is possible to have a route statement send traffic to subnet 192.168.64.0 out interface VLAN1? I'm not sure if this will work because VLAN1 is not a Layer3 interface.
Thanks in Advance,
