11 | Following tests are covered to test multicast pim6 sm: | |
12 | ||
13 | Test steps | |
14 | - Create topology (setup module) | |
15 | - Bring up topology | |
16 | ||
17 | Following tests are covered: | |
18 | 1. Verify Multicast data traffic with static RP, (*,g) and | |
19 | (s,g) OIL updated correctly | |
20 | 2. Verify mroute detail when receiver is present | |
21 | outside of FRR | |
22 | 3. Verify (*,G) and (S,G) populated correctly | |
23 | when FRR is the transit router | |
24 | 4. Verify (S,G) should not create if RP is not reachable | |
25 | 5. Verify modification of mld query timer should get update | |
26 | accordingly | |
27 | 6. Verify modification of mld max query response timer | |
28 | should get update accordingly | |
29 | 7. Verify removing the RP should not impact the multicast | |
30 | data traffic | |
