When two routers exchange database information through DD messages, a master-slave relationship is first formed. The one with the larger DR Priority becomes the master router, and its master-slave bit is determined to be MS.

• A.FALSE
• B.TRUE

When BGP establishes a peer connection, both this segment and the peer end will initiate a TCP three-way handshake, so two TCP connections will be established. However, in actual BGP, only one of the TCP connections will be retained. Obtain the peer BGP from the Open message. After Identifier, the BGP peer will compare the size of the local Router ID and the peer Router ID. If the local Router ID is smaller than the peer Router ID, it will be closed. The locally established TCP connection will use the TCP connection actively initiated by the peer. Subsequent BGP message exchange.

• A.FALSE
• B.TRUE

In the network shown in the figure, R1 and R2 run IS-IS and establish an adjacency relationship. The Loopback0 interface of R2 enables IS-IS, and the Loopback3 interface of R2 does not enable IS-IS. Under the IS-IS process of R2, do as follows Which of the following statements about the configuration shown in the figure is correct? (Multiple choice)

• A.There is a route of 10.0.2.3/32 in the routing table of R1
• B.The routes 10.0.2.2/32 and 10.0.2.3/32 do not exist in the routing table of R1
• C.There is a route of 10.0.2.2/32 in the routing table of R1
• D.The route 10.0.2.3/32 does not exist in the routing table of R1
