Route Policy Configuration Example
Applying a Route Policy to IPv4 Route Redistribution
Network Requirements
z
As shown in the following figure, Switch B exchanges routing information with Switch A using
OSPF, and with Switch C using IS-IS.
z
On Switch B, enable route redistribution from IS-IS to OSPF and apply a route policy to set the cost
of route 172.17.1.0/24 to 100, and the tag of route 172.17.2.0/24 to 20.
