pimd: OIF add with PROTO_PIM is not happening if join rxed in PP state
Dumps while in problem state -
============================
[from "show ip pim state"]
Active Source Group RPT IIF OIL
1 6.0.0.31 239.1.1.111 n swp1 swp4( J * )
[from "show ip pim join"]
Interface Address Source Group State Uptime Expire Prune
swp3 6.0.0.22 6.0.0.31 239.1.1.111 JOIN --:--:-- 03:11 --:--
You can see from the dumps that the pim downstream router has joined on
swp3 but that OIF has not been added to the OIL with flag
PIM_OIF_FLAG_PROTO_PIM. This is because the join was rxed while the
ifchannel was in a prune-pending state.
Relevant logs -
