Hi

I think there are issues with IGMPv3. I suggested IGMPv4 some time = ago.

I think that some issues are:

1. Mixing include and exclude sources -> information of sources of = SSM (source specific multicast) is lost when mixing and PIM router can = not use SSM
2. Separating include / exclude -> group timer and exclude list are = not neccessary
3. No exclude list -> all the timers of exclude sources =3D0 -> no = need for timers in exclude sources
4. No need for timers in Include sources when the routers keeps = information of every host and channel -> no include timers (the = reason is in GMI)
5. no exclude timers + no include timers -> timers are not necessary = -> everything is much simpler,

1,2,3,4,5 -> the state machine of the router is decribed with 8 lines = (without source timers, group timers, exclude lists and Q(G,S))

regards

Alvaro

PS. BCP79/ more than 10 applications filed in USPTO / first one will be = isued in 12 days.
