why route for reserved multicast address don't show up in sh ip mroute? is reserved multicast address route propagation limited to the given broadcast/nonbroadcast network only? i.e. assume followings scenario. assume PIM-SM is enabled on all routers and R5 is RP. assume eigrp is running on r3-r4 link only. why r1,r2,,r5,r6 can't ping eigrp mcast address 224.0.0.10?
r1-r2-r3-r4-r5-r6
