Description of PR

Summary:
Fixes # (issue)

Implement the BGP Bounce Back Routing test script

Type of change

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

Approach

What is the motivation for this PR?

The BGP Bounce Back Routing (BBR) feature has been introduced into SONiC.
This change is to implement a test script for testing this BGP BBR feature.

How did you do it?

This test requires T1 type topology. Added 3 test cases:

Test Case1

  • BBR is enabled (by default), announce a route to the first T0 VM. The route has DUT asn in aspath.
  • Verify that the route is accepted by DUT and propagated to other VMs.

Test Case2

  • BBR is enabled (by default), announce a route to the first T0 VM. The route has two DUT asn in aspath.
  • Verify that the route is not accepted by DUT and not propagated to other VMs.

Test Case3

  • Disable BBR, announce a route to the first T0 VM. The route has DUT asn in aspath.
  • Verify that the route is not accepted by DUT and not propagated to other VMs.
  • Enable BBR again after test.

How did you verify/test it?

Test run the script on vs setup running t1-lag topology and 201911 image.

Any platform specific information?

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

t1 type topology

[ VRF ] Returned t0 configuration for run vrf cases (#2580)
d8ad002 
As described in #2538, when run vrf test suite "AnsibleUndefinedVariable: 'dict object' has no attribute 'podset_number'" appears. The reason is that these attributes were deleted from topo_t0.yml by commit #1233

Changes:
* Removed all hardcoded values from fib plugin.
* Added missed params to all topo files
* Updated generate_routes method, removed hardcoded values for decap case.
