[qpimd-users] self as a neighbor

[Andrew Lunn]

Hi folks

Is the daemon supposed to have itself as a neighbor?



uml1> show ip pim neighbor
Recv flags: H=holdtime L=lan_prune_delay P=dr_priority G=generation_id 
A=address_list
            T=can_disable_join_suppression

Looking at the logs, i think it is receiving its own multicasted Hello
message and not discarding it.

maybe related, the next line in the log is:
