Which statement is correct about the prefix 160.0.0.0/8?
A.
The prefix has encountered a routing loop.
B.
The prefix is an aggregate with an as-set.
C.
The prefix has been aggregated twice, once in AS 100 and once in AS 200.
D.
None of these statements is true.
Explanation:
The as-set keyword within an aggregate-address will set all AS which the more-specific routes
have passed to the point where the aggregate-address has been configured. Without this
keyword, the aggregate address would only show the passed AS’ from the point where the
aggregate-route has been configured.
