Description of PR
UDP sport 53 is a special port to be used in DNS and there is a rule in test server ovs switch
It would forward packet with UDP sport 53 to VM instead of to PTF port due to an existing ovs rule:
cookie=0x0, duration=8133.286s, table=0, n_packets=0, n_bytes=0, idle_age=8133, priority=8,udp,in_port=3,tp_src=53 actions=output:1Summary:
Fixes # (issue)
When UDP outer sport == 53, the packet would not be received at PTF ports in fib/test_fib.py::test_vxlan_hash test
Type of change
Back port request
Approach
What is the motivation for this PR?
When UDP outer sport == 53, the packet would not be received at PTF ports in fib/test_fib.py::test_vxlan_hash test
How did you do it?
Exclude 53 from the port range
How did you verify/test it?
Run it in local setup
Any platform specific information?
Supported testbed topology if it's a new test case?
