24 | Following tests are covered to test multicast pim sm: | |
25 | ||
26 | Test steps | |
27 | - Create topology (setup module) | |
28 | - Bring up topology | |
29 | ||
30 | Following tests are covered: | |
31 | ||
32 | 1. TC:48 Verify mroute after configuring black-hole route for RP and source | |
33 | 2. TC:49 Verify mroute when RP is reachable using default route | |
34 | 3. TC:50 Verify mroute when LHR,FHR,RP and transit routers reachable | |
35 | using default routes | |
36 | 4. TC:52 Verify PIM nbr after changing interface ip | |
37 | 5. TC:53 Verify IGMP interface updated with correct detail after changing interface config | |
38 | 6. TC:54 Verify received and transmit hello stats are getting cleared after PIM nbr reset | |
