Hi all,
Below is cut from the CISCO web site
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/ip_r
/iprprt3/1rdmulti.htm#xtocid1674448
"You must configure the IP address of RPs on all routers (including the RP
router).
First-hop routers send register packets to the RP address on behalf of
source multicast hosts. Routers also use this address on behalf of multicast
hosts that want to become members of a group. These routers send Join and
Prune messages towards the RP. The RP must be a PIM router; however, it does
not require any special configuration to recognize that it is the RP. Also,
RPs are not members of the multicast group; rather, they serve as a "meeting
place" for multicast sources and group members"
The above statement say that IP address of RP must be configure on all
routers (including the RP router) but later the statement also mention that
the RP router does not require any special configuration to recognise that
it is the RP. So does it mean that the RP router must configure with "ip
pim rp-add" or not?
I'm confuse with these, can anyone please me to clear this up?
Thanks.
