Network Requirements
■ Switch B exchanges routing information with Switch A via OSPF, with Switch C
via IS-IS.
■ On Switch B, configure route redistribution from IS-IS to OSPF and apply a
routing policy to set attributes of redistributed routes, setting the cost of route
172.17.1.0/24 to 100, tag of route 172.17.2.0/24 to 20.
