OSPF Test Cases

[asraza07]

Summary

Add test case code for OSPF functionality according to OSPF test plan

Type of change

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

Approach

Motivation for this PR

To add PyTest test case code in accordance with previously contributed OSPF test plan

How I did it

Added a new folder directory 'sonic-mgmt/tests/ospf/' containing the following files:

• conftest.py containing setup/teardown plugins
• test_ospf.py containing 2 test cases:
  • Test OSPF Neighborship
  • Test OSPF Dynamic Routing

Platform specific information

These test cases have been written to run on testing topologies with SONiC-type neighbors. Once the code is tested and verified, code to support Arista-type neighbors will be developed as well.

Supported testbed topologies

These test cases support the following topologies:

• T0
• T1

@StormLiangMS Hi, Can you please help review this test case. Target is 202405 release. Thanks in advance for help!

Sanity Testing for Test Case 1 - test_ospf_neighborship

I have manually performed the steps outlined in test_ospf_neighborship() on T0 which can be seen in the screenshots below. It can be seen that OSPF neighborship is successfully established and redistributed routes are available to the DUT shared from neighboring devices.

Sanity Testing for Test Case 2 - test_ospf_dynamic_routing

I have manually performed the steps outlined in test_ospf_dynamic_routing() on T0 where after configuring OSPF neighborship, a Loopback interface was created on ARISTA01T1 and the route shared to the DUT. It can be seen in the screenshots below that the Loopback route is available to the DUT, and then link failure was simulated by removing the Loopback interface, after which the route is not seen by the DUT anymore.
