Help with c877 DSL configuration

Unanswered Question
Jun 18th, 2010

I have a C877 DSL router that I am trying to connect as a linknet so that I can run an igp on it to route my public ip's and private networks back through the DSL. Here is a bad ASCII drawing.

Cisco877 --------------- Lucent Stinger DSL ------------------ Cisco3750 L3 switch
              |               Aggregator                |
             DSL                                  GigE interface Vlan 142

I have this working  by using a BVI interface on the 877 DSL WAN (ATM0).  See current configurations.

My problem is that I need to shape on the 877 as well as configure QOS (VoIP lives behind the 877) which from my understanding is not supported on BVI interfaces.
Is there some other way to set this up so that I can both shape and do QOS on the DSL?



I have this problem too.

Hello J,

unfortunately given the need for IRB you cannot use another type of interface you should look for applying QoS tools on internal interface

you are using RFC1483 bridge mode

Hope to help
