Abstract
The invention provides main and spare routing equipment, a backup and switch method between the equipment and a routing system. The backup method between the main and spare routing equipment comprises the following steps that: the main routing equipment sends a learned address resolution protocol table item of a user to the spare routing equipment according to a preset rule before the main and spare routing equipment is switched; and the spare routing equipment receives and learns the address resolution protocol table item. According to the method provided by the invention, the main routing equipment sends the learned address resolution protocol table item of the user to the spare routing equipment before the main and spare routing equipment is switched, such that the spare routing equipment can learn the address resolution protocol table item of the user in advance; when the main and spare routing equipment is switched, because of learning the address resolution protocol table item of the user, the spare routing equipment can directly forward downlink flow of the user according to the address resolution protocol table item; and thus, the switch speed between the main and spare routing equipment is increased.
