Re: PIM Bsr hash value

Hi
Err will we asked to be calculate the hash-mask-length value in:
ip pim bsr-candidate [hash-mask-length] [priority]
Because the following just goes way over my head:

Input: Group Address (G), RP-Set (R1, R2 Rn), Mask. This information
is used as the input to the hash funcation. R1, R2.. Rn are IP
addresses of the RPs mapped to the Group address G. The Mask is
calculated based on the mask-length distributed by the BSR.

1) Among the routers in RP-Set, select those that have numerically
lowest priority values. By default all cRPs advertise priority of
zero, so they all are eligible.

2) For every RP IP address, calculate the hash function value:

value1 = Hash(G&Mask, R1),
value2 = Hash(G&Mask, R2) 
valueN = Hash(G&Mask,Rn).

Anthony forgive my ignorance here but I cant quite grasp what you are
saying in step 1 and 2.
