TUN-1.9: GRE inner packet DSCP

Summary

Verify the DSCP value of original packet header after GRE acl based tunnel encapsulation.

Procedure

  • Configure DUT with ingress and egress routed interfaces.
  • Configure acl based tunnel configuration with action as encapsulation.
  • Attach the filter on ingress interface.
  • Configure the static route for the tunnel end point destination.
  • Capture packet on ATE on the recieving end(port-2).
  • verify dscp value of original packet after encapsulation.
  • verify that no traffic drops in all flows.

OpenConfig Path and RPC Coverage

Validation coverage

  • No packet drop should be oberserved.
  • Capture the packet on recieving end and verify the orginal DSCP value. Orginal value should not be altered.
