[j-nsp] Multicast configuration

[Harry Reynolds]

I might me mistaken here, but I seem to recall that static joins in JUNOS
software would generate S,G state, but would not actually flood traffic out
the associated interface unless a real join was received. IOW, the
downstream interface for the static join may be pruned.

What app are you using on the PC, and can it generate a real join?  We use
wsend/wlisten in classes.

HTHs again.
