so the code currently returns the RP for simplicity and it simply picks 
the RP with the highest node ID (or equivalent to highest IP address) to 
be the RP for all groups.
	You can simply just replace the hash function above with another, 
more sophisticated hash function, similar to the one we presented in the 
PIM-SM specification, or in the bootstrap paper.
	[for more details and links on this check either the PIM web page

hope this helps,
