Description

Few of the voq end to end tests fail. The tests are : voq/test_voq_ipfwd.py::TestVoqIPFwd::test_voq_end_to_end_ping, voq/test_voq_ipfwd.py::test_ipforwarding_jumbo_to_dut and few of test_voq_disrupts testcases.

The loopback route advt are getting filtered ( by RH route-maps) on the T2 chassis based on the BGP neighborship type as RegionalHub/AZNGHub -- If the DEVICE_NEIGHBOR_METADATA type is RegionalHub the loopback ip is filtered

This results in ping failure from T1 --> T3 as the reachability to loopback is not present in routing table for those "type" BGP neighbors. Mostly we should be able to fix this in tests - checking on that.

Steps to reproduce the issue:

1. Run voq/test_voq_ipfwd.py::TestVoqIPFwd::test_voq_end_to_end_ping, voq/test_voq_ipfwd.py::test_ipforwarding_jumbo_to_dut

Describe the results you received:
End to End ping failure

Describe the results you expected:
ping should pass
