thats right..
i used send-rp-announce and rp-discover/rp-filter commands as follows on the
hub..

ip pim send-rp-announce Loopback0 scope 16 group-list 55
ip pim send-rp-discovery Loopback0 scope 16
ip pim rp-announce-filter rp-list 23 group-list 55
!
access-list 23 permit 4.4.5.5
access-list 55 permit 224.1.1.1

One spoke router has an ethernet interface joining 224.1.1.1 but the spokes
dont have their mroute tables populated..Any idea whats going on..

r2#sh ip mroute 224.1.1.1
Group 224.1.1.1 not found

r2#sh ip mroute
