Thanks.
One more question, how does the other non-RP PIM routers learn of the
RP-to-group mapping ? Do they listen to a multicast group just like auto-RP
does ? Your given link seems does not cover it about.
regards,
alec

Hi Alec,
The concept behind BSR is essentially the same as Auto-RP. The
candidate-RP's inform the BSR of the group-to-mapping and then the BSR tells
all the other routers. One difference is that a BSR is elected from the
group of potential BSR's.
There are some very good resources that go into detail about this. See
http://www.cisco.com/univercd/cc/td/doc/cisintwk/intsolns/mcst_sol/rps.htm
Also, see
http://www.cisco.com/warp/public/732/Tech/multicast/multicast_techdoc.shtml
In addition, Doyle's Routing TCP/IP vol II and Willianson's book, Developing
IP Multicast Networks provide excellent, comprehensive information on these
topics.
HTH, dt
