Route Maps
If the statement is marked as permit and the packets do not match any route-map statements, the packets are
sent back through the normal forwarding channels and destination-based routing is performed.
Route Maps
You can use route maps for route redistribution or policy-based routing. Route map entries consist of a list
of match and set criteria. The match criteria specify match conditions for incoming routes or packets, and the
set criteria specify the action taken if the match criteria are met.
You can configure multiple entries in the same route map. These entries contain the same route map name
and are differentiated by a sequence number.
You create a route map with one or more route map entries arranged by the sequence number under a unique
route map name. The route map entry has the following parameters:
• Sequence number
• Permission—permit or deny
• Match criteria
• Set changes
By default, a route map processes routes or IP packets in a linear fashion, that is, starting from the lowest
sequence number. You can configure the route map to process in a different order using the continue statement,
which allows you to determine which route map entry to process next.
Match Criteria
You can use a variety of criteria to match a route or IP packet in a route map. When Cisco NX-OS processes
a route or packet through a route map, it compares the route or packet to each of the match statements
configured. If the route or packet matches the configured criteria, Cisco NX-OS processes it based on the
permit or deny configuration for that match entry in the route map and any set criteria configured.
The match categories and parameters are as follows:
• IP access lists—(For policy-based routing only). Match based on source or destination IP address, protocol,
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:
• Policy-based routing only—Change the interface or the default next-hop address.
Licensing Requirements
The QoS feature does not a require license. Any feature not included in a license package is bundled with the
Cisco NX-OS system images and is provided at no extra charge to you.
