Question 1

The following description of the characteristics of multi-instance CE is ?

Options :

A : Since the MCE device is already bound to the VPN, there is no need to bind the VPN on the PE connected to the MCE device

B :

The MCE device can determine the source of the routing information according to the interface that

receives the routing information, and maintain it in the route forwarding table of the corresponding VP.

C :

MCE is implemented by creating their own routing forwarding tables for different VPNs on the MCE

device and binding to the corresponding interface o

D :

Configuring MCE enables a CE to connect to multiple VPNs at the same time, which can not only

completely isolate the service between different VPN users, but also reduce the input cost of network

equipment.

Answer: A

C : after the BPDU protection function is enabled on the switching device, if the edge port receives RST BPDU, the edge port will be set to a non-remote port and the spanning tree calculation will be re-performed

D : Start the specified port of root protection, when the port receives a better RSTBPDU, the port will enter the Discarding state and is no longer forwarding packets. If the port does not receive a better RSTBPD for a period of time then automatically revert to the normal Forwarding state
