If you don't need to access the vlan at the intermediary routers a psudo-wire may work.
I have only used them via mpls but understand they work with encapsulation l2tpv2 or 3 as well. ________________________________ From: Pavel Dimow <[email protected]> To: [email protected] Sent: Sat, February 12, 2011 10:13:02 AM Subject: [c-nsp] How to pass VLAN through router Is this possible at all? I ended in pretty ugly scenario (for a short time period I hope) where I must pass VLAN through router (yes router not L3 switch). The scenario is: SW1-----trunk-----R1-----trunk-----R2-----trunk-----L3SWITCH I don't have control over SW1 and R1, but I do know that I have trunk from my R2 to other side R1 for sure (I already terminate one VLAN on R2). Now, I need somehow to get VLAN from other side (SW1) to L3SWITCH where I will setup a SVI. Any thoughts? How router behaves considering VLANs? Is it only possible to terminate vlan on subinterface and no vlan passing? It is logical to me, because router is a router not a switch (in my case R2 is Cisco ASR). And IF router will pass VLAN over trunk interfaces how do I control which VLANs are allowed to pass over which interface? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
