We have a customer that is relocating thier headquarters. They have a temporary requirement to bridge multiple vlans or a router T3 link to the new location as they cannot change the IP subnets. Setup is 3560 switch connecting to a 3845 then T3 to remote 3845 and 3560. I need to bridge multiple VLANs. I have seen a good example on how to do it over sonet but I don't see how to translate that to an HDLC or Frame Relay encapsulation for the T3 Link. I need to know if this can be done and if so any examples on hw to do it would be great!!

David, see this discussion.. it may help, look into l2tpv3.

Wlll give L2TPv3 a try.

These posts are very old and the link that you offered is no longer any good. I needed some help with L2TPv3 and was hoping that someone was still monitoring this forum. I have two routers and wanted to run L2tpv3 so that I could extend by VLANS. Can anyone give me a quick overview of how to actually configure L2TPv3 on these two MPLS routers?

Can you post your configuration on the routers? If they are MPLS routers you can also use EoMPLS in lieu of L2TPv3. Here's a doc that explains how to configure l2tpv3.

I have the following routers
Router 1
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 192.168.192.20 YES NVRAM up up
FastEthernet0/1 63.232.181.14 YES NVRAM up up
FastEthernet0/3/0 10.1.1.3 YES NVRAM up up
NVI0 192.168.192.20 YES unset up up
Multilink88 65.102.24.102 YES NVRAM administratively down down
Router 2
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0 10.4.52.10 YES NVRAM up up
GigabitEthernet0/1 172.31.150.2 YES NVRAM administratively down down
Serial0/0/0:0 unassigned YES NVRAM up up
Serial0/0/1:0 unassigned YES NVRAM up up
Serial0/1/0 unassigned YES NVRAM up up
Multilink1 65.102.24.134 YES NVRAM up up
Both of these routers are MPLS routers at separate locations, I understand that I need to create a pseudowire-class l2tp-auto entry, but would I do it on my g0/0 interface on router 2 since that is the vlan I want to extend from that router? And would I create a simular entry on router 1
FastEthernet0/3/0 since that is the vlan I want it to reach? I appreciate all help.
Thanks
