Multicast PIM neighbor filter

When two PIM enabled neighbor routers exchange Hello packets at regular intervals, they become
PIM neighbors by default. This feature enables a router to have more control on which routers can
be its neighbors by specifying an IP access-list. The access list denies PIM Hello packets from the
source it wants to filter, thereby preventing that router.

Feature requirement

This feature requires the assistance of the already existing ACL feature to filter out the traffic, in the
form of PIM Hello packets, from unwanted PIM neighbors.
