Test steps
- Create topology (setup module)
- Bring up topology
TC_1 : Verify upstream interfaces(IIF) and join state are updated properly
after adding and deleting the static RP
TC_2 : Verify IIF and OIL in "show ip pim state" updated properly after
adding and deleting the static RP
TC_3: (*, G) Mroute entry are cleared when static RP gets deleted
TC_4: Verify (*,G) prune is send towards the RP after deleting the static RP

becomes unreachable
TC_7 : Verify upstream interfaces(IIF) and join state are updated properly
after adding and deleting the static RP
TC_8: Verify (*,G) prune is send towards the RP when RP becomes unreachable
TC_9 : Verify RP configured after IGMP join received, PIM join towards RP is
sent immediately
TC_10 : Verify RP becomes reachable after IGMP join received, PIM join
towards RP is sent immediately
TC_11 : Verify PIM join send towards the higher preferred RP
TC_12 : Verify PIM prune send towards the lower preferred RP

FHR router
TC_23 : Verify (*,G) and (S,G) populated correctly when RPT and SPT path are
different
TC_24 : Verify (*,G) and (S,G) populated correctly when SPT and RPT share the
same path
TC_25 : Verify (*,G) and (S,G) populated correctly after clearing the PIM ,
IGMP and mroutes joins
TC_26 : Restart the PIMd process and verify PIM joins , and mroutes entries
TC_27 : Configure multiple groups (10 grps) with same RP address
TC_28 : Configure multiple groups (10 grps) with different RP address
TC_29 : Verify IIF and OIL in updated in mroute when upstream interface
configure as RP
TC_30 : Verify IIF and OIL change to other path after shut the primary path
TC_31 : Verify RP info and (*,G) mroute after deleting the RP and shut / no
shut the RPF interface.
TC_32 : Verify RP info and (*,G) mroute after deleting the RP and shut / no
shut the RPF inteface
