[Xorp-hackers] Extension of PIM: Register stop

[Ralf Lübben]

Hello,

I'm new to XORP.

At the moment I'm trying to extend PIM. For it I need to understand how the 
switch between the different phases in PIM (RP Tree -> Register Stop -> 
Shortest Path Tree) is done.

I saw that all packets are forwarded to the PIM process if the flag 
VIFF_REGISTER is set. 
But I can't find the code where the flag is reset, so that multicast packets 
are no longer forwarded from the kernel to the PIM process.

Maybe someone can give me a hint.

Thanks in advance.

Regards,
Ralf
