Is it at all possible to run more than 1 virtual circuit over a single DSL/FTTC link?<br><br>
Basically sometimes customers of ours will be running 2 VRFs (guest wireless, whatever). It's very easy to separate these 2 VRFs over the WAN using subinterfaces on the primary ethernet link. However the DSL/FTTC backup interface can only be part of one VRF
because there is only one virtual-circuit.<br><br>
Any ideas? I've tried to run multiple pppoe sessions over a DSL link before and it never allowed me to have more than 1 active at any one time.<br><br>Thanks<br></div></div><br>
