[qpimd-users] Problem resolved: querry related with qpimd code (read last few lines)

Hello Everton and friends,

    It seems that those lines where pim_rpf is called in ifmembership_set
function. The code from where it is called is resolved.

Regards,
Bhavin.

Hello Everton and friends,

      As i was saying i was getting some error with the previous
version, now i am trying do some analysis of log reports. While
looking at log reports i see some difference in calling some functions
as shown below:

    As we see the two logs we can see that below lines do not come in
older quagga:
1999/10/04 18:40:50 PIM: pim_rpf.c pim_nexthop_lookup: found nexthop

to eth0

   Even while looking at code i could not find when pim_rpf or even the
pim_zlookup (which is in both of the logs) in pim_forward_start function
in pim_zebra.c in pimd directory. Can you tell me please when those pim_rpf
and pim_zlookup are called while receiving any igmp ssm packet.

   Thanks in advance for your help.
