Hi Saptanshu,

The first example is to filter the two groups used in Auto-RP (224.0.1.39 it's
where they advertise themselves and 224.0.1.40 is used for discovery purposes)
it's very used in Service Providers imagine you have your routers learning
Auto-RP requests and you don't want this advertisiments to cross your border
routers otherwise you might end up learning Auto-RP from a router that is not
yours.

The second one accomplish the same thing (filtering learning of candidate RPs
but for BSR (aka PIMv2).

HTH,
