A、 OSPF stub areas increase the size of the LSDB with the addition of Type 3 and 5 LSAs B、 OSPF not so stubby areas are particularly useful as a simpler form of summarization C、 OSPF stub areas are always insulated from external changes D、 OSPF totally stubby cannot distinguish among ABRs for the best route to destinationsoutsidethe areas E、 OSPF stub areas can distinguish among ASBRs for destinations that are external to the OSPFdomain
A、the kind of OSPF areas being implemented B、the number of external LSAs in the network C、the number of DRs and BDRs in the areas D、the number of virtual links in the areas E、how well the areas can be summarized F、the use of LSA filters
A、In interface configuration mode, the OSPFv3 area ID combination assigns interfaces to OSPFv3 areas. B、In router configuration mode, the network wildcard area ID combination assigns networks to OSPFv3 areas. C、In interface configuration mode, the IPv6 OSPF process area ID combination assigns interfaces to OSPFv3 areas. D、In router configuration mode, the IPv6 OSPF interface area ID combination assigns interfaces to OSPFv3 areas.
A、The area cannot be a backbone area. B、Inter area routes are suppressed. C、The area has no more than 10 routers. D、No virtual links are allowed. E、No autonomous system border routers are allowed. F、Redistribution is not allowed unless the packet is changed to a type 7 packet.
A、They are used to summarize area routes to other areas. B、They are used in not-so-stubby areas to propagate external routes. C、They are used to notify areas of the ASBR. D、They are flooded to all areas except stub areas (external route).
A、A. All OSPF routers in stubby areas can have type 3 LSAs in their database. B、B. All OSPF routers in stubby areas can have type 7 LSAs in their database. C、C. All OSPF routers in totally stubby areas can have type 3 LSAs in their database. D、D. All OSPF routers in totally stubby areas can have type 7 LSAs in their database. E、E. All OSPF routers in NSSA areas can have type 3 LSAs in their database. F、F. All OSPF routers in NSSA areas can have type 7 LSAs in their database.
A、A. All OSPF networks require the use of multiple areas B、B. Multiple OSPF areas must connect to area 0 C、C. Single area OSPF networks must be configured in area 1 D、D. Areas can be assigned any number from 0 to 63535 E、E. Area 0 is called the backbone area F、F. Each OSPF area need to be configured with a loopback interface
