Override ASNs in outbound updates if AS-Path
equals Remote-AS | You might use the BGP AS override feature
if you have multiple sites belonging to the same AS (AS 64512, for
example) and there is another AS between them. A router between
the two sites receives an Update advertising a route that can access
AS 64512. To avoid the second site dropping the Update because it
is also in AS 64512, the intermediate router replaces AS 64512 with
its own ASN, AS 64522, for example. |
