With the following configuration, OSPF external routes with tags 1, 2, 3, and 5 are redistributed into RIP
with metrics of 1, 1, 5, and 5, respectively. The OSPF routes with a tag of 4 are not redistributed.

Given the following configuration, a RIP learned route for network 172.18.0.0 and an ISO-IGRP learned
route with prefix 49.0001.0002 will be redistributed into an IS-IS Level 2 LSP with a metric of 5:

route-map 1 permit

The following configuration example illustrates how a route map is referenced by the
default-information router configuration command. This type of reference is called conditional default
origination. OSPF will originate the default route (network 0.0.0.0) with a type 2 metric of 5 if
172.20.0.0 is in the routing table.
route-map ospf-default permit
