802.1q between two facilites

Unanswered Question
Jul 22nd, 2007

I have two sites connected with an E1. Is there any way to setup interavlan routing between the sites? They are connected with 2610's, which can be swapped out if needed

I have this problem too.

Do you have a real need to carry vlans in bridging across the E1 ? Usually that is not recommended.

The normal setup is hence that you configure different subnets for each VLAn in each site. The routers will have subinterfaces on FA0/0 with the corresponding "encapsulation dot1q ". Then normal routing on the E1 (HDLC) and with static or dynamic routing.

Note that if you keep the 2610 for intervlan routing, do not expect wire-speedperformance when going from a vlan to another within the same site. There should be no performance issues when going across E1.

Hope this helps, please rate post if it does!
