Enable/Disable parameter. Default is enabled.
This is used to activate a RP Register process to
efficiently handle forwarding of encapsulated PIM
Register packets. One process is created for sending
to each RP. If this is disabled, the default PIM_REGISTER
process will be used. With PIM_REGISTER forwarding, each
time we have to do 2 lookups; one for searching the RP table
for destination group, the other for RP route lookup
