Hello danger.highvoltage@hotmail.com ,

I don't think you can configure on a packet over Sonet POS interface service instances and bridge domains that are commands available on Ethernet based LAN interfaces.

A POS is a sync serial interface not a LAN interface

 

Hope to help

how to bridge two POS interfaces

Hello @WaisAhmadMirwais60647 ,

if they do not support the modern command syntax with bridge domains and service instance I am afraid you cannot bridge over POS interfaces.

 

Many years ago I used the first forms of IRB to perform bridging between LANs using routers connected with a serial interface but it was using the old syntax of bridge-group.

 I performed several type of tests over POS interfaces but I have never tried to configure bridging.

 

POS is IP packets over SONET/SDH and it was introduced as a great semplification in comparison to ATM interfaces using Sonet/SDH for high speed point to point links with also reduced overhead.

 

Hope to help

Giuseppe
