Re: Query about the Amount of Multicast State information

Each (S,G) has multiple timers, outgoing interface list that may be
constantly changing etc.... Overall, an entry in the mroute table could
require a lot of overhead in the control-plane. A BGP route on the other
hand is basically stateless, a prefix is learned and installed into the
RIB, nothing else happens with it until the neighbor it was learned from
goes down or an update is received.
