A. No routes are redistributed because a route cannot be both E1 and E2.

B. Only OSPF E2 routes in the OSPF 2 domain will be considered for redistribution.

C. Inside the OSPF 2 domain, any formerly E2 routes will become E1 routes.

D. Routes permitted by ACL 1 will be redistributed, regardless of whether the routes are E1 or E2 routes.

- map fred with the redistribute ospf 2 command. R1 has learned intra - area routes for 10.1.1.0/24 and10.1.2.0/24 in part due to the Type 2 LSAs known for each subnet. The route map filters route 10.1.1.0/24 and allows 10.1.2.0/24 througH.Which of the following co mmands on router R1 list subnet 10.1.1.0/24？（）

A. show ip route

B. show ip eigrp topology

C. show ip ospf topology

D. show ip eigrp topology 10.1.1.0/24

C． IS - IS

D． OSPF

E． EIGRP

A. ABR

B. ASBR

C. internal router

D. backbone router

Route redistribution (RR) has become an integral part of IP network design as the res ult of a growing need for disseminating certain routes across routing protocol boundaries. By default, which description is true when redistributing routes from other routing protocols into OSPF？（）

A. Summarized routes are unacceptable

B. They will appe ar in the OSPF routing table as type E2 routes

C. Only routes with lower administrative distances will be imported

D. All imported routes are to be automatically summarized if possible

es are redistributed into the OSPF domain. A second redistribu tion is configured on router R2 using a route map. Based on the configuration on router R2, which EIGRP external routes will be present in the routing table of R1？（）

A. the routes originating from the RIP routing domain

B. the routes originating from the OSPF stub area

C. all OSPF inter and intra - area routes

D. all routes originating from RIP and OSPF routing domains

rk. One route is from EIGRP and has a composite metric of 20514560. Another route is from OSPF with a metric of 782. The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table？（）

A. the OSPF route

B. the EIGRP route

C. the RIPv2 route

D. all three routes

E. the OSPF and RIPv2 routes

A.edit policy-options policy-statement policy-name set term 1 from protocol static set term 1 then accept

B.edit ospf policy set from protocol static set 1 then accept

C.set protocols OSPF export policy-name

D.set protocols OSPF policy policy-name
