[Xorp-users] multicast questions!

[G.T. Chiang]

Dear All
   we are tring to make our network multicast working. we had test using 
mtrace, and seems the problme seems happend at our gateway machine. this is 
our architecture.

sender machine---gateway (two interfaces)---university router----

we are running xorp at gateway machines. however, when i run show pim 
neighbors, it is empty. it seems the router can not find next hop:( any one 
can give us any suggestion? the folloiwng is our xorp configuration file. 
we do not rellay know whihc RP have to use, it should be the closese one to 
our gateway? or we should to ask university netwokr people? BTW, it seems 
the unicast and multicast when we run traceroute, it is using different 
router just outside our network, will that be a problme?
