Network Requirements
In Figure 300, Router B exchanges routing information with Router A using OSPF,
and with Router C using IS-IS.
Configure route redistribution on Router B to redistribute IS-IS routes into the
OSPF routing domain, and use a routing policy to set attributes for redistributed
routes. Set the cost of route 172.17.1.0/24 to 100, and the tag of route
172.17.2.0/24 to 20.
