Chapter 34 Configuring IP Unicast Routing
You can also identify route-map statements as permit or deny. If the statement is marked as a deny, the
packets meeting the match criteria are sent back through the normal forwarding channels
(destination-based routing). If the statement is marked as permit, set clauses are applied to packets
meeting the match criteria. Packets that do not meet the match criteria are forwarded through the normal
routing channel.
Although each of Steps 3 through 14 in the following section is optional, you must enter at least one

Purpose
Enter global configuration mode.
enter route-map configuration mode.
map-tag—A meaningful name for the route map. The
redistribute router configuration command uses this
name to reference this route map. Multiple route maps
might share the same map tag name.
(Optional) If permit is specified and the match criteria
are met for this route map, the route is redistributed as
controlled by the set actions. If deny is specified, the
route is not redistributed.
sequence number (Optional)— Number that indicates the
position a new route map is to have in the list of route
maps already configured with the same name.
Match a BGP AS path access list.
Match a BGP community list.
Match a standard access list by specifying the name or
number. It can be an integer from 1 to 199.
Match the specified route metric. The metric-value can be
an IGRP five-part metric with a specified value from 0 to
4294967295.
Match a next-hop router address passed by one of the
access lists specified (numbered from 1 to 199).
Match the specified tag value in a list of one or more route
tag values. Each can be an integer from 0 to 4294967295.
Match the specified next hop route out one of the
specified interfaces.
Match the address specified by the specified advertised
access lists.
