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.
