How to send VLAN Tags across Routers

joopdog11
Level 1
Level 1

I have two 1841 routers that are connected over a dedicated T1 line. I would like to be able to extend the vlan information on one network to the other. So basically I would like to be able to use a trunk link over the T1.

Is this possible?

Switch-----Router-----Router-------Switch
vlan1                  T1                 vlan2
vlan2                                      vlan5
vlan5

The T1 is our point to point connection across two cities.

How can I have vlan2 and vlan5 across both routers?

Any help would be appreciated.

Thanks

Have a look at this document for example:  It is called Transparent bridging

http://www.cisco.com/en/US/tech/tk331/tk660/technologies_tech_note09186a0080094471.shtml

You can intead keep the vlans diiferent in each location and use the routers to route your vlans.

Is this the way?

EoMPLS - check daunderground.net for details. It's easy and scales well.
