Indicates Paths Requiring
Periodic Flood-Prune Cycles
for a Given Multicast Group
These multicast routers do
not have the state refresh
feature and thus require
periodic flood-prune
cycles to advertise active
multicast group. In this
case it may be better to
group these routers on the
same multicast tree to
avoid the additional flood/
prune cycles on the routers
that do support state
refresh.
These ProCurve 5300xl multicast
routers support the state refresh
feature but must handle periodic
flood-prune cycles for the
downstream routers that lack this
These ProCurve 5300xl multicast
routers support the state refresh
feature and do not require periodic
flood-prune cycles for a given
multicast group, which frees up
bandwidth for other uses.
