A.After this command is configured, BGP only sends the aggregated route to the peer.

B.This command is used to enable automatic aggregation of locally imported routes.

C.This command is used to implement automatic aggregation. It has a higher priority than manual aggregation.

D.After this command is configured, BGP aggregates routes according to the natural network segment.

E.After this command is configured, BGF no longer receives the subnet routes advertised by IGP. Therefore, the number of routing information can be reduced.

A.The cost of the external route of the second type is only the external cost of AS, and the internal cost of the AS is ignored.

B.AS-Externa|-LSA describes the path to the external route of the AS. The scope of the flooding is outside the AS.

C.AS-Externa|-LSA describes the path from the router to ASBR.

D.AS-Externa|-LSA does not belong to any area.

A.The DD packet sent in the ExStart state contains the link state description.

B.Negotiate the master-slave relationship in the ExStart state. After confirming the master-slave relationship, the master router sends DD packets, and the slave router cannot actively send DD packets, which can only respond to DD packets sent by the master router.

C.The Full status indicates that the LSDBs of the two routers have been synchronized.

D.In the Loading state, the routers send DD packets containing the summary of the link state information to describe the contents of the local LSDB.

A.The route must be an IGP route

B.The route must exist in the IP routing table and is the best route

C.The mask length must be strictly matched

D.Match the prefix, the mask length does not have to match exactly

A.Join/Prune

B.Assert

C.Bootstrap

D.Register
