A.Each router directly learns routes from the update messages and adds these routes to the routing table.

B.Each router individually builds a picture of the entire flooding domain.

C.The router sends all link state information received from one neighbor to all the other neighbors, ensuring database synchronization.

D.Routers in the entire flooding domain have the same link state database.

E.Routers in the flooding domain may repeatedly receive the same link state information.

A.Configure routing policies on R2. Default route filtering.

B.R2 system-ID R3 conflict

C.R2 system-ID R1 conflict

D.R3 R4 and the area of the regulation error

A.The sender advertises the size of the initial window.

B.If the sender does not receive an acknowledgment message after the retransmission timer times out, it retransmits the unacknowledged data.

C.The sliding window size can only be increased or remains unchanged.

D.A TCP sliding window allows the sender to send multiple data packets before receiving an acknowledgment message.

E.The sender does not need to transmit packets with a complete window size.

A.By default, all the routers on the router and PE VPNv4 assign the same label value to the route that is sent.

B.MPLS BGP VPN: Two-layer labels are used in ( ) ( ). Public network labels are also called layer labels and private network labels. They are also called layer labels.c

C.When the private network is transmitted by the label MP-BGP or LDP, the route carries the route and the public network is sent by the label protocol.

D.Export In the judgment of the export PE CE, the inner label is used for reporting.

A.WRED can prevent UDP from occupying too much bandwidth during congestion

B.Completely eliminates congestion

C.Provides minimal bandwidth guarantees

D.Avoids TCP synchronization

E.Provides bounded low latency
