Multiple candidate RPs
I was working on IEWBvol1 Multicast section and came across page.64 where a design with multiple RPs was discussed.
I've yet to figure out why (and how) the logic works...I think these two sentences look somehow contradictory: (copy and paste from the text)
1- "For overlapping ranges MA will only advertise the RP with the highest IP address"
2- "Notice that the mapping list is copiles by the MA but still the final RP selection is performed by multicast routers." <the longest match criterion>
As you see it's not clear that whether both or just one of the candidates would be offered to routers in the network. So if for a particular range I introduce more than one cRP who's gonna be the actual RP?
