Approach

What is the motivation for this PR?

• When the test_bgp_session_flap is run on T2 duts connected to vsonic neighbors, the following error occurs and the test fails.
  filename = '/data/tests/bgp/test_bgp_session_flap.py' function_name = 'setup' index = 0 line_number = 96 lines = [' nbrhosts[tor1]["host"].eos_command(commands=["show run | section bgp"])))\n'] module_args = [] module_async = False module_ignore_errors = False previous_frame = <frame at 0x3eb6080, file '/data/tests/bgp/test_bgp_session_flap.py', line 96, code setup> res = {'failed': True, 'msg': 'Connection type ssh is not valid for this module', '_ansible_no_log': None, 'changed': False} self = <SonicHost VM2902> verbose = True common/devices/base.py:131: RunAnsibleModuleFail</error>

• Fix the above error, by adding vsonic support to the test.

How did you do it?

• Make sure, test handles dut connected to both ceos and vsonic neighbors.

How did you verify/test it?

• Ran all the above-mentioned test cases on a T2 chassis and made sure tests passed with expected behavior.

Any platform specific information?

Supported testbed topology if it's a new test case?
