NO.38 When a router forwards an IPv6 packet, it needs to look up the routing table according to the source IP address of the IPv6 packet.

NO.39 In the network shown in the figure below, the network administrator hopes that the data packets sent from host A to host B will pass through the G0/0/3 interface between the routers when the network administrator performs traffic planning, and the data packets sent from host B to host A will pass through the router Which of the following commands can achieve this requirement on the G0/0/4 interface?
