Set Changes

Once a route or packet matches an entry in a route map, the route or packet can be changed based on one
or more configured set statements.
The set changes are as follows:
•
•
•
•

Access Lists

IP access lists can match the packet to a number of IP packet fields such as the following:

•
•
You can use ACLs in a route map for policy-based routing only. See the Cisco Nexus 7000 Series NX-OS
Security Configuration Guide, Release 4.x for more information on ACLs.

AS Numbers for BGP

You can configure a list of AS numbers to match against BGP peers. If a BGP peer matches an AS
number in the list and matches the other BGP peer configuration, BGP creates a session. If the BGP peer
does not match an AS number in the list, BGP ignores the peer. You can configure the AS numbers as a
list, a range of AS numbers, or you can use an AS-path list to compare the AS numbers against a regular
expression.

AS-path Lists for BGP

You can configure an AS-path list to filter inbound or outbound BGP route updates. If the route update
contains an AS-path attribute that matches an entry in the AS-path list, the router processes the route
based on the permit or deny condition configured. You can configure AS-path lists within a route map.
You can configure multiple AS-path entries in an AS-path list by using the same AS-path list name. The
router processes the first entry that matches.
