it will be helpful if you can post out a sample topological diagram representing the devices, connectivity (with router,switch)you have at present to have more clarity about the kinda setup you have in place.

Hello,

you could use a dynamic routing protocol like EIGRP or OSPF across both links to remote router(s). Depending on the metric you set, you will use either link as long as it is up. a failure would result in rerouting the traffic accross the working link.

You should post more detailes regarding your setup, topology and hardware used to allow for more specific help.

Hope this helps anyhow! Please rate all posts.

Hi

in this figure the customer have one ip 16 ip block that is oruted with IGRP in PE router

we want either link customer use same ip block.

and in RF link Base Station is connected in L3 Swith Fast Eternet port.

All rf customers are in different VLANS.

if the LeaselIne went down the traffic will automatically swithed over to rf link

means the L3 swith fast ethernet port have several vlan membership in this it automatically go.

sorry for poor english.

looking forward u r reply.

thanks
