The protocol uses the P/

mechanism to speed up the upstream port's transition to the Forwarding state, but what is the reason for no temporary loop? ()

Ensure that there will be no temporary loops through the synchronization mechanism

Reduced the time of ForwarD. Delay

An interface priority is 0, then the interface cannot be a DR

DR must be the highest priority device in the network

Router ID, the larger the value, the more preferred it is to be elected as DR

An interface priority is 0, then the interface cannot be a DR

sourceIP is 192.168.1.1, destination P is 172.16.10.1, and all TCP packets with destination port number 21 match this rule

The source IP is 192.168.1.1, the destination IP is 172.16.10.2, and all 1CP packets whose destination port number is 21 match this rule

Rule sourceIP is 192.168.1.1, the destination IP is 72.16.10.3, and all TCP packets with the destination port number of 21 match this rule

If the DHCP client and the DHCP server are not on the same network segment, the DHCP relay needs to be used to forward DHCP messages

network does not allow multiple DHCP servers

After receiving the DHCP request or response message, the DHCP relay does not modify the message format and forwards it directly

If the DHCP client and the DHCP server are not on the same network segment, the DHCP relay needs to be used to forward DHCP messages

DHCP client and DHCP server must be connected to the same switch
