True or False: When IS-IS is redistributed into OSPF via:

router ospf 100
redistribute isis level-1-2 subnets

some IS-IS routes may not be redistributed successfully. Specifically, routes advertised using IS-IS on the redistributing router are not redistributed. If a directly connected network is also advertised by IS-IS, the route is entered into the local routing table as a connected route and not as an IS-IS route. While redistributing IS-IS into OSPF, these directly connected routes are not injected into OSPF and you must also use the following command to inject the routes into OSPF:

router ospf 100
redistribute connected subnets
