I have a 3845, that I need to run to two different 3550 switches, while maintaining the same vlan across both switches, The only way I can think to do this is IRB with the router trunk subinterfaces? Is there another way?
Also, my company have an internal OSPF network, I need to tunnel differnet customer network thorugh my core. Can VRF work in this environment so I can separate the customer routing tables? Does anyone have a example of this confg/
