mroute and route

[petercinvest]

we are using Pim sparse mode, my router R5 don't have route to my RP. my RP ip address is 172.16.2.0, 

so in R5, i have two choice: (1) ip route  172.16.2.0 255.255.255.0 E2/0 or (2) ip mroute 172.16.2.0 255.255.255.0 E2/0

should i use option 1 or option 2? so my R5 can reach RP, thanks

Hi

You have to use choice 1 becuase the router need to know how to send packets to the rp for regisstration.

Choice 2 is only used for rpf (return path check) , if mcast packets is coming from an interface other than what the unicast routing table shows.
