3.
redistribute protocol [process-id] {level-1 |
level-1-2 | level-2} [metric metric-value]

To disable redistribution, use the no form of the commands.
EXAMPLE
Given the following configuration, a RIP-learned route for network 160.89.0.0 and an ISO IGRP-learned route with prefix
49.0001.0002 will be redistributed into an IS-IS Level 2 link-state PDU with metric 5:
router isis
redistribute rip route-map ourmap
redistribute iso-igrp remote route-map ourmap
route-map ourmap permit
match ip address 1
match clns address ourprefix
set metric 5
set level level-2
access-list 1 permit 160.89.0.0 0.0.255.255
clns filter-set ourprefix permit 49.0001.0002...
Configuring Policy-Based Routing
You can use policy-based routing (PBR) to configure a defined policy for traffic flows. By using PBR, you can have more
control over routing by reducing the reliance on routes derived from routing protocols. PBR can specify and implement
routing policies that allow or deny paths based on:
Identity of a particular end system
Application
Protocol
Purpose
Enter global configuration mode.
Enter router configuration mode.
Redistribute routes from one routing protocol
to another routing protocol. If no route-maps
are specified, all routes are redistributed. If the
keyword route-map is specified with no
map-tag, no routes are distributed.
Cause the current routing protocol to use the
same metric value for all redistributed routes
(BGP, RIP, and OSPF).
Cause the EIGRP routing protocol to use the
same metric value for all non-EIGRP
redistributed routes.
Return to privileged EXEC mode.
Display all route maps configured or only the
one specified to verify configuration.
(Optional) Save your entries in the
configuration file.
