RT-1.11: BGP remove private AS 

Summary

BGP remove private AS

Procedure

• Establish BGP sessions as follows between ATE and DUT.
  • ATE emulates two eBGP neighbors peering with the DUT using public AS numbers.
    • DUT Port1 (AS 500) ---eBGP--- ATE Port1 (AS 100)
    • DUT Port2 (AS 500) ---eBGP--- ATE Port2 (AS 200)
  • Inject routes with AS_PATH modified to have private AS number 65501 from eBGP neighbor #1 (ATE Port1).
  • Validate received routes on ATE Port2 should have AS Path "500 100 65501".
  • Configure "remove private AS" with type PRIVATE_AS_REMOVE_ALL on DUT.
  • Validate that private AS numbers are stripped before advertisement to the eBGP peer ATE Port2.
  • AS path for received routes on ATE Port2 should be "500 100".
  • TODO: different patterns of private AS should be tested.
    • AS Path SEQ - 65501, 65507, 65554
    • AS Path SEQ - 65501, 600
    • AS Path SEQ - 800, 65501, 600

      TODO : https://github.com/openconfig/featureprofiles/issues/1659

      SET mode is not working in ATE.

    • AS Path SET - 800, 65505, 600
