A.The priority of the bridge is 16 bits in total, and the value range is 0-65535

B.The smaller the priority value, the lower the priority of the bridge

C.The step size of bridge priority is 4096

D.If the switch is not configured with the priority of the bridge, the default value is 32768

A.Hello

B.Prune

C.Join

D.Assert

E.Graft

F.Graft-ACK

A.Different multicast sources take themselves as the root and establish SPT independently

B.In the SPT model, the path taken by the multicast source to reach any receiver is optimal

C.Each router on the SPT will maintain (S, G) entries

D.Each router on the SPT will maintain (*, G) entries

A.The backup group uses real MAC mode

B.The backup group vrid is 5

C.The backup group uses virtual MAC mode

D.The vrid of the backup group is 4

A.If STP wants to shorten the convergence time, you can only configure a smaller ForwardDelay time, but it may affect the stability of the network

B.Compared with STP, RSTP defines the edge port, which can make the port connected to the i machine quickly enter the forwarding state

C.Compared with STP, RSTP defines a fast root port switching mechanism^ This can make Alternate quickly become a new root port

D.Compared with STP, RSTP defines the designated port fast switching mechanism, which can make the designated port quickly enter the forwarding state without waiting for twice the Forward Delay time
