AS Path Set#

Routing Policies → APAS Path Sets

The ASPathSet resource groups one or more autonomous system numbers (ASNs) and can be referenced by a routing policy to match a route that has none, any, or all of these AS numbers.

Match options#

Whether the route is matched if all, any, or none of the members are found in the route's AS path is determined by the Policy statement, not the ASPathSet.

Members of the ASPathSet are regexes, which are checked against either the entire AS path or the individual AS numbers (see section about regex modes).

Regex modes#

When regexMode is set to ASN, each ASN is treated as a single element that is matched against the member regexes defined in the ASPathSet. If regexMode is set to Character, the route's entire AS path is treated as a string and matched character by character, similar to traditional regex matching.
