24 | Following tests are covered to test BGP basic functionality: | |
25 | ||
26 | Test steps | |
27 | - Create topology (setup module) | |
28 | Creating 4 routers topology, r1, r2, r3 are in IBGP and | |
29 | r3, r4 are in EBGP | |
30 | - Bring up topology | |
31 | - Verify for bgp to converge | |
32 | - Modify/Delete and verify router-id | |
81e3d609 AP |
33 | - Modify and verify bgp timers |
34 | - Create and verify static routes | |
35 | - Modify and verify admin distance for existing static routes | |
36 | - Test advertise network using network command | |
37 | - Verify clear bgp | |
38 | - Test bgp convergence with loopback interface | |
39 | - Test advertise network using network command | |
19f4da0b KK |
40 | - Verify routes not installed in zebra when /32 routes received |
41 | with loopback BGP session subnet | |
