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
Refer to the exhibit. Will redistribute d RIP routes from OSPF Area 2 be allowed in Area 1? () A. RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.B. Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.C. Redistrib uted RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.D. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.E. Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.
