Hi,
I have the following scenario:
Switch -Trunk- Layer3 Switch which connects to another router âRouterBâ on FE with no IP addresses
Certain vlans from the switch carried over the trunk are terminated on Layer3 Switch, however I want to bridge vlan 100 across to RouterB where it will be terminated.
How do I do this?

Hello Hadi,
depending on the model of L3 switch you could be able to use L2Tpv3.
vlan based 802.1Q you can decide on a per vlan basis if you want to terminate or to transport to the other side
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t2/feature/guide/gtl2tpv3.html#wp1043064
between two switches you can also think to use 802.1q tunneling but you would need a dedicated interface for vlans to be carried between the two sites
Hope to help

Thanks for your help Giuseppe, The L3 Switch we use is 6524 that is connected to a 2811ISR.
BTW Isn't there an easier way to do this instead of configuring L2TP? It seems a bit complex for transporting a vlan across a router.
