Hi Rafael,

As you know, all else being equal, Autorp prefers the RP with the
highest IP address. However, I think you will find that the mask on
the group-list comes before highest IP in the decision algorithm.

Try something like this:

R5:

access-list 10 permit 224.10.10.10 (host mask)

R6:

access-list 10 permit 224.10.10.0 0.0.0.255 (/24 mask)

Not sure if this approach is within the rules of your task. But it is
an option to consider. Check it out.
