HWIC-4SHDSL-E router back to back connection

[acbennyma]

Hello expert,

I have two site that has a copper wire (2 wire) connection between each router ( No Telco in between )

Now I want to use 1921 router with HWIC-4SHDSL-E card to connect these two ste together.

Can I use attach configuration to make the connection reference from the diagram?

Hello Acbennyma,

interfaces that are member of a bridge-group cannot have an IP address, using IRB as you would like to do you can have an IP address only on the BVI1 logical interface.

The LAN interface and the ATM interface are just members of the bridge-group with no L3 configuration.

Besides this, the configuration of CO side looks like reasonable

Hope to help

Giuseppe
