Hi Jian,
No.These commands are not redundant.
"ip pim send-rp-announce loopbakc 0 scope 16
group-list [my list]" tells the router about which
groups the router is willing to act as RP.The second
command filters the RP Announcements at the mapping
agent.It means that mapping agent can ignore the
candidate rp announcement from router X.
