Description of PR

This PR provides enhancement in the existing test plan for BFD with echo-mode. The test plan comprises of one test case:

1. Test case BFD Echo Mode

Type of change

Added a new test plan to run BFD echo-mode along with BGP routing protocol.

• Bug fix
• Testbed and Framework(new/improvement)
• Test case(new/improvement)

Approach

What is the motivation for this PR?

Currently, there is no existing test plan for running BFD echo-mode in SONiC. This test plan helps the user configure BFD echo-mode in the existing testbed and framework.

How did you do it?

This test case uses the existing BGP configurations for routing purpose. BFD neighborship is established between DUT and its neighboring devices. Once BFD neighborship is established then BFD echo-mode is enabled on DUT and its neighboring devices.

How did you verify/test it?

Run the test case on any topology.

Any platform specific information?

It will run on all topologies where neighboring devices are SONiC devices.

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