Hi @satish-kotapati and @pradeeptakdas ,
Would it be possible to set up a quick call to walk us through the use cases and design behind this change?

Following are the meeting notes and action items discussed on Jun 26, 2026

Attendees: [skotapati], [Ajith Nambiar], [Parthiban Selvaraj], [Augusto Seganfredo Mainardi], [Tina Elizabeth Chacko], [Akhila Reddy], [Pradeepta Kumar Das]

As per the guidance from the component owners (Augusto and Parthiban), [Ajith Nambiar] should review the implementation in the following file and update the code accordingly:
https://github.com/rdkcentral/utopia/blob/develop/source/service_routed/service_routed.c and there is no requirement to introduce msb.wanmanager.RoutingTableName in the WAN Manager code.

If any architectural changes are identified, they should be discussed in the RDK-B WAN Working Group meeting.

We will wait for [Ajith Nambiar] to complete the analysis and provide feedback.
