The router that doesn't have ip pim rp-address is the rp itself, it
doesn't need the command.
A beneficial command is "show tech ipmulticat" on both routers. Be sure
to be in enable mode when issuing it and it will also give us the
configs. Does R2 has S0 in the outbound interface list for the multicast
group? Is E0 listed in the outbound interface for R1? Send us the "show
tech ipmulticast" output from both routers and we can take a look.
