Hi,
The wording of the question is different from the one you've stated:
AS400 will not provide transit for TRAFFIC COMING FROM AS54 and its customers
THAT IS DESTINED for AS254.
You have to think of this in a reverse fashion. We are talking about traffic,
not prefixes! Traffic follows the opposite way of the prefixes.
So this means that the prefixes advertised by AS254 will not get forwarded by
AS400 to AS54 and customers. You have several ways of performing this...
Imagine, if I'm on AS54 and I wish to reach AS254, I need to have a prefix
advertised to my routing table by AS400. Only after knowing my destination I
can send traffic to it.

ok i don't like the wording of this task at all.
as400 should not advertise prefixes learned from as54 and connected
customers to AS254. however, if you have to configure filtering of the
AS54 prefixes, it will effect as300 and as100 as well., and i don't like
this. this task must be worded wrong. can anyone clarify??
