=> This is exactly why I urge you (this wg) to clearly 
explain which protocol you are talking about. AR - AR or
AR MN ???
Clearly AR - MN lis an obvious way to discover all routers 
that the MN can hear. Inter/intra domain issues are 
not relevant. 

So please make it clear which part of the protocol
you're referring to. We should not always assume 
that we're discussing the AR - AR case.

=> Certainly. But there is an easy way of doing that:
Let the MN decide.
