Failed to run pytest when neighbor device is SONiC

[xjasonlyu]

Description

Failed to complete a pytest when using SONiC image as the neighbor devices.

Steps to reproduce the issue:

1. Setup testbed step by step based on KVM Testbed Setup
2. Choose SONiC image as the neighbor devices
3. Run a pytest, e.g. ./run_tests.sh -n vms-kvm-t0 -d vlab-01 -c bgp/test_bgp_fact.py -f vtestbed.csv -i veos_vtb -e "--neighbor_type=sonic"

Describe the results you received:

Error message says the VM0100 doesn't have a valid interface Ethernet1 (because Ethernet1 doesn't exists in SONiC VM).

@xjasonlyu can you confirm that you are deploying (add-topo) with -k vsonic specified? Could it be that you deployed a testbed with ceos but trying to run test with setting neighbor type to sonic? @Pterosaur can help you further.

Hi @xjasonlyu , it's a known issue that is being fixed by PR sonic-net/sonic-buildimage#8971 and #4341. Please check the sonic image of neighbor devices includes the PR sonic-net/sonic-buildimage#8971 and manually merge the PR #4341 to sonic-mgmt repo.
