Re: More than one EIGRP AS on the same Router Question

Loc,

Thanks,

I know about meeting the lab requirements and even to
be doubly sure of whatever I see and do not see.

I was just wondering if there any thing to be aware of
when using this technique that might be strange that I
had not yet noticed.

I've also used the various protoccols with the same AS
on one router, a given AS is separated and even though
the same AS is used, they are not intended to be
connected, etc.

I guess I'm really wondering if I saw a given scenario
like this with EIGRP specifically, if there are any
given caveats that might influence my decision to pose
a question to the proctor, that might indicate an
alternate solution involving redistribution with BGP
or even using another protocol, but not using mutual
redistribution between two EIGRP AS's.

(I probably can't even say "Hi" and be brief any
more).
