[Xorp-hackers] New OSPF assert, probably related to FEA.

[Pavlin Radoslavov]

Before sending the join_multicast_group XRL, the OSPF process is
suppose to be registered by using the register_receiver XRL.
If for some reason it has unregistered (e.g., by sending
unregister_receiver) or because the FEA unregistered it on its own,
then you will get the "not registered" error.

Hope that helps debugging the problem.
