EIGRP and IGRP are both Interior Gateway Protocols that are used inside a
AS. Therefore, when you want to connect different AS'es, you need an
Exterior Gateway Protocol like BGP. Within BGP you are routing to different
AS'es therefore the AS'es should be unique.
Therefore: EIGRP AS 1 ---- IGRP AS 50 ---- EIGRP AS 1 will not work.

Subject: RE: EIGRP contiguous AS
If I remember correct, AS numbers do not have to be contiguous unless if you
want automatic redistributing between EIGRP and IGRP. If you have different
AS across boundaries then you will need to have to manually redistribute...

Subject: EIGRP contiguous AS
I have an interesting question for the group, although
it is not directly related to any of the current
exams.
Does an EIGRP AS have to be contiguous or can it be on
two sides of an IGRP 'AS'. I note that the use of the
term AS is a mis-nomer for both protocols, but...
For example, does:
EIGRP AS 1 ---- IGRP AS 1 ---- EIGRP AS 1
pose a problem?
Does:
EIGRP AS 1 ---- IGRP AS 50 ---- EIGRP AS 1
My belief is that it could work, but it breaks the
concept of an AS and could lead to routing topology
table problems. Any takers?
(I'll be working with my team in the lab, but thought
it was an interesting thought questions.)
Nothing but net!
