Routers 2 and 3 have been configured as candidate RPs, and multicast RP announcements to 126.96.36.199. Router 1 is the RP. R1 sees the candidate RP announcements from R2 and R3, and designates R3 the RP because it has a higher IP address (188.8.131.52). R1 multicasts the RP mapping to 184.108.40.206. The capture is from the R1-R2 link.
