Routing policy configuration examples
Routing policy configuration example for IPv4 route
redistribution
Network requirements
As shown in Figure 101, Switch B exchanges routing information with Switch A by using OSPF and
with Switch C by using IS-IS.
On Switch B, enable route redistribution from IS-IS to OSPF, and use a routing 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.
