It doesn't really matter. AS numbers in EIGRP are only relevant when
there's some overlap between the routers in the two ASes, so that those
routers can configure the appropriate settings for each group. Since
the two ASes are disjoint, the AS numbers can be arbitrary, and it
doesn't matter if they're the same or not.
