11 | Following tests are covered to test BGP basic functionality: | |
12 | ||
13 | Test steps | |
14 | - Create topology (setup module) | |
15 | Creating 4 routers topology, r1, r2, r3 are in IBGP and | |
16 | r3, r4 are in EBGP | |
17 | - Bring up topology | |
18 | - Verify for bgp to converge | |
19 | - Modify/Delete and verify router-id | |
81e3d609 AP |
20 | - Modify and verify bgp timers |
21 | - Create and verify static routes | |
22 | - Modify and verify admin distance for existing static routes | |
23 | - Test advertise network using network command | |
24 | - Verify clear bgp | |
25 | - Test bgp convergence with loopback interface | |
26 | - Test advertise network using network command | |
19f4da0b KK |
27 | - Verify routes not installed in zebra when /32 routes received |
28 | with loopback BGP session subnet | |
