Configuring IP Unicast Routing
Beginning in privileged EXEC mode, follow these steps to configure a route map for redistribution:
Command
Step 1
configure terminal
Step 2
route-map map-tag [permit | deny]
[sequence number]
Step 3
match as-path path-list-number
Step 4
match community-list
community-list-number [exact]
Step 5
match ip address {access-list-number |
access-list-name} [...access-list-number |
...access-list-name]
Step 6
match metric metric-value
Step 7
match ip next-hop {access-list-number |
access-list-name} [...access-list-number |
...access-list-name]
Step 8
match tag tag value [...tag-value]
Step 9
match interface type number [...type
number]
Step 10
match ip route-source
{access-list-number | access-list-name}
[...access-list-number |
...access-list-name]
Step 11
match route-type {local | internal |
external [type-1 | type-2]}
Step 12
set dampening halflife reuse suppress
max-suppress-time
Step 13
set local-preference value
Step 14
set origin {igp | egp as | incomplete}

Purpose
Enter global configuration mode.
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 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 EIGRP
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.
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.
Set BGP route dampening factors.
Assign a value to a local BGP path.
Set the BGP origin code.
