I have the following topology
I have MSDP connection between RP1 and RP3. I expected to ping from S-2 to R-1. Can I do that ?
S-2#ping 220.127.116.11 (18.104.22.168 is registered from R-1)Type escape sequence to abort.Sending 1, 100-byte ICMP Echos to 22.214.171.124, timeout is 2 seconds:

10.100.112.22 is configured on S-2.
Any insights ? what have I missed ?
thanks a lot !!
You missed the multicast TTL, default is 1.
ping 18.104.22.168 ttl 20
TTL is 255
ge-0/0/2 on both RPs should be configured to be pim sparse mode ?
inter domain RPs need to be pim neighborship ?
