Trunking router to multiple switches and VRF questionss

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/

You can define access port on switch in (for example) vlan 300 and connect it to router . On router port you can create ip address- so this is another- but in my opinion not better way. After that you should connect you switches witj trunk port with alloved vlan 300. Bartosz Gagat
