A.The specified introduced RIP routing route is marked as 33.

B.The specified introduced RIP route metric as 50.

C.The router OSPF process number is 40.

D.The specified introduced RIP route is a Type 2 external route.

A.Can avoid routing loops caused by inappropriate routing feedback

B.Cannot avoid sub-optimal routing caused by route introduction

C.You can influence routing by modifying the attributes of the route

D.Can be used for precise route import and route advertisement control

A.True

B.False

A.Each OSPF device collects the LSA which sent by other routers. All the LSA are put together to form the link state database LSDB.

B.The LSDB of all routers in OSPF area 0 are the same.

C.According to the directed graph, each router uses the SPF algorithm to calculate a shortest path tree rooted at itself. This tree gives the routes to each node in the autonomous system.

D.OSPF uses the link state algorithm.

E.Each router advertises local link state information through flooding LSAs.

A.In BGP routing rules, the priority of MED is higher than Local-Preference, that is the priority is compared with MED.

B.In BGP routing rules, the priority of Preferred-Value is higher than Local-Preference, that is the priority is compared with Preferred-Value.

C.BGP route the default value of Local-Preference is 100.

D.BGP Local-Preference is usually used in the routing rule policy to control how data flows into As
