VLANS, Switches and Bridging

In a switched network can routers be used for bridging? We have sites that are not on the fiber backbone. We are using Pairgains and routers to bridge the sites into their VLAN. Ip routing is off on the routers. Will this cause problems on the network??

Re: VLANS, Switches and Bridging

Routers can be used to bridge. Most only routers only pass 1500 byte frames so you will not be able to bridge dot1q or ISL frames. Spanning-tree is important consideration. You most likely need to run a hierachical spanning-tree where the switches run IEEE STP and the routers run DEC.
