[c-nsp] Multicast Problems

[Peter Salanki]

My networks looks like this: Sender on a peer-as-(MSDP,PIM-SM)>RP- 
ROUTER->ROUTER->CLIENT

RP-Router Running: 12.2(18)SXD6
Router: 12.2(18)SXD3
They are c6500-supervisor2

I have added correct mroutes to the sources.

When I try to join a group on CLIENT which is origined by peer-as,  
everything seems nice on RP-ROUTER:
c6509-tule#sh ip mroute 239.255.102.2

c6509-tule#

On ROUTER, things look pretty ok too:
c6509-sterik#sh ip mroute 239.255.102.2
....

(*, 239.255.102.2), 00:17:35/00:02:51, RP 213.80.98.4, flags: S
   Incoming interface: Vlan300, RPF nbr 85.24.151.1, Partial-SC
   Outgoing interface list:
     Vlan4, Forward/Sparse, 00:17:35/00:02:51

c6509-sterik#

The group won't show up in "sh ip mroute active" on c6509-sterik  
(ROUTER) but it shows in c6509-tule (RP-ROUTER)

Routing of groups where sources are directly connected to c6509- 
sterik (ROUTER) works fine, even when clients are not directly  
connected. Routing from c6509-sterik (ROUTER) to clients through the  
RP doesen't seem to work though.

Thanks for any tips
