… Up ( Case 2)
Description of PR
Summary:Adding BGP convergence for single session flap testcase with Port UP and Route Injection
Fixes # (issue)
Type of change
Back port request
Approach
What is the motivation for this PR?
To implement the BGP case 2, as part of the Snappi-based BGP Convergence Test
How did you do it?
This case flaps one of the Rx port up and injects route from one of the Rx port
How did you verify/test it?
Tested with 2 BT0s and 1 BT1
Any platform specific information?
Supported testbed topology if it's a new test case?
