Chapter 31 Configuring IP Unicast Routing
Configuring Protocol-Independent Features
Beginning in privileged EXEC mode, follow these steps to configure a route map for redistribution:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
route-map map-tag [permit | deny] [sequence number] Define any route maps used to control redistribution and
enter route-map configuration mode.
map-tag—A meaningful name for the route map. The
redistribute router configuration command uses this
name to reference the 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 of a new route map in the list of route maps
already configured with the same name.
Step 3
match as-path path-list-number Match a BGP AS path access list.
Step 4
match community-list community-list-number [exact] Match a BGP community list.
Step 5
match ip address {access-list-number |
access-list-name} [...access-list-number |
...access-list-name]
Match a standard access list by specifying the name or
number. It can be an integer from 1 to 199.
Step 6
match metric metric-value Match the specified route metric. The metric-value can be
an IGRP 5-part metric with a value from 0 to 4294967295.
Step 7
match ip next-hop {access-list-number |
access-list-name} [...access-list-number |
...access-list-name]
Match a next-hop router address passed by one of the
access lists specified (numbered from 1 to 199).
Step 8
match tag tag value [...tag-value] Match the specified tag value in a list of one or more route
tag values. Each can be an integer from 0 to 4294967295.
Step 9
match interface type number [...type number] Match the specified next hop route out one of the specified
interfaces.
Step 10
match ip route-source {access-list-number |
access-list-name} [...access-list-number |
...access-list-name]
Match the address specified by the specified advertised
access lists.
Step 11
match route-type {local | internal | external [type-1 |
type-2]
Match the specified route-type:
• local—Locally generated BGP routes.
• internal—OSPF intra-area and interarea routes or
EIGRP internal routes.
• external—OSPF external routes (Type 1 or Type 2)
or EIGRP external routes.
Step 12
set dampening halflife reuse suppress
max-suppress-time
Set BGP route dampening factors.
Step 13
set local-preference value Assign a value to a local BGP path.
Step 14
set origin {igp | egp as | incomplete} Set the BGP origin code.
