RT-1.1: Base BGP Session Parameters

Summary

BGP session establishment between DUT - ATE and verifiying different session parameters.

Topology

DUT port-1 -------- ATE port-1

Procedure

Test the abnormal termination of session using notification message:

• Establish BGP session between DUT (AS 65540) and ATE (AS 65550). The DUT/ATE peers should be configured with MD5 authentication using the same password.

  • Ensure session state should be ESTABLISHED.
  • Verify BGP capabilities: route refresh, ASN32 and MPBGP.

• Verify BGP session disconnect by sending notification message from ATE.

  • Send CEASE notification from ATE.
  • Ensure that DUT telemetry correctly reports the error code.

Test md5 password authentication on session establishment:

• Configure matching passwords on DUT and ATE. Verify that BGP adjacency succeeds.

• Configure mismatched passwords on DUT and ATE. Verify that BGP adjacency fails.

Test the normal session establishment and termination:

• Establish BGP session for the following cases:

  • eBGP using DUT AS 65540 and ATE AS 65550.
    • Specifies global AS 65540 on the DUT.
    • Specifies global AS 65536 and neighbor AS 65540 on the DUT. Verify that ATE sees peer AS 65540.
  • iBGP using DUT AS 65536 and ATE AS 65536.
    • Specifies global AS 65536 on the DUT.
    • Specifies both global and neighbor AS 65536 on the DUT.

  And include the following session parameters for all cases:

  • Explicitly specified Router ID.
  • Explicit holdtime interval and keepalive interval.
  • Explicit connect retry interval.
