I am trying to configure a 1811 router to do inter-vlan routing for my SLM2024 switch. Going thru previous posts, it advised setting one port, which is not associated with any vlans, with link aggregation. Afterwards, join that port to the vlans with tagging enabled which will be used as their trunk port. I have setup subinterfaces on one of the router's fast ethernet interfaces with dot1q encapsulation. So far the routing is still not working. Can you guys suggest anything that might be missing?
