Here's a new bug for you Stig.

What if you have two C-RPs both advertising the same group range, but
one is bidir and one is ASM?

Since the RP address is a subset of the encoded group range, you have
to pick one or the other.

And the BSR has to recognize this and either reject the C-RP from the
bidir or asm RP or make the great leap of faith and choose whether the
group is bidir or ASM for itself.

(Oh, of course, one could weasel out of it and say it was a  
misconfiguration)

3.6 talks about whether or not a given router can support bidir and asm

but there are no other references that describe which one has priority.

Can I suggest bidir should always win.  :-)
