A.The routers in the entire flooding domain have the same road data.

B.Each router establishes a topology structure for the entire flooding domain.

C.The router in the flooding domain may repeatedly receive the same road information chain.

D.The router will send all the existing road information to all other neighbors to send the wrong state to the neighbor, and the data synchronization certificate.

A.Huawei devices support flow-based port mirroring. The mirrored traffic can be copied onto multiple observing ports

B.Huawei devices support port mirroring on the control traffic sent to the CPU

C.When the observing port becomes congested, mirrored packets cannot be discarded because these packets have higher priority than service traffic

D.Traffic in the RSPAN is transmitted to observing ports in multicast mode
