10 | Following tests are covered to test PIM BSM processing basic functionality: | |
11 | ||
12 | Test steps | |
13 | - Create topology (setup module) | |
14 | - Bring up topology | |
15 | ||
16 | Tests covered in this suite | |
17 | 1. Verify FRR router select higher IP BSR , when 2 BSR present in the network | |
18 | 2. Verify BSR and RP updated correctly after configuring as black hole address | |
19 | 3.1 Verify when new router added to the topology, FRR node will send | |
20 | unicast BSM to new router | |
21 | 3.2 Verify if no forwarding bit is set , FRR is not forwarding the | |
22 | BSM to other PIM nbrs | |
23 | 3.3 Verify multicast BSM is sent to new router when unicast BSM is disabled | |
53c7a86e | 24 | 4.1 Verify BSM arrived on non bsm capable interface is dropped and |
df94c7e8 KK |
25 | not processed |
26 | 4.2 Verify group to RP info updated correctly in FRR node, after shut and | |
27 | no-shut of BSM enable interfaces | |
28 | 5. Verify static RP is preferred over BSR | |
29 | 6.1 Verify adding/deleting the group to rp mapping and RP priority | |
30 | multiple times | |
31 | 6.2 Verify RP and (*,G) detail after PIM process restart on FRR node | |
32 | 7.1 Verify BSM timeout on FRR1 | |
33 | 7.2 Verify RP state in FRR1 after Bootstrap timer expiry | |
34 | 8.1 Verify upstream interfaces(IIF) and join state are updated properly | |
35 | after BSM received for FRR | |
36 | 8.2 Verify IIF and OIL in "show ip pim state" updated properly after | |
37 | BSM received | |
