An OSPF non-backbone area allows external routes to be flooded within the area. These externalroutes are propagated into other areas. However, external routes from other areas are not allowed to enter this area. Which type of OSPF area does this describe?（）A. stub areaB. transit areaC. border areaD. not-so-stubby area
考题
What type of OSPF router is responsible for redistributing routes into OSPF?()
A. ABRB. ASBRC. internal routerD. backbone router
考题
Why would you make a non－backbone area a stub or not－so－stubby area?()
A. to aggregate routes learned from the ABRB. to lower the cost of routes advertised by the ABRC. to connect a non-contiguous area to the backboneD. to decrease the size of the link-state database in that area
考题
