Approach
What is the motivation for this PR?
In Azure network, Netscan uses IP-decap to check for route blackholes, but servers do not support decapsulation, making it impossible to perform server-to-server checks. To address this, we developed the subnet decap feature to detect if the link between the server and T0 is functioning properly. Additionally, new test cases are required to ensure the functionality of subnet decap is working as expected.
Sever to T0 test was added in #14720, we need to add server to T1 test
