Kind Code:
B2
Abstract:
This application relates to the communications field, and in particular, to a method and gateway for obtaining a route according to a requirement. In the method for obtaining a route according to a requirement, a first gateway receives a first packet; the first gateway searches a forwarding table for a next hop of a first IP address in the first packet, wherein the search fails; the first gateway sends a second packet carrying the first IP address to at least one gateway, where the second packet is used to instruct a gateway receiving the second packet to determine whether a host identified by the first IP address accesses a network by using the gateway receiving the second packet; the first gateway receives a third packet from a second gateway, where the third packet is used to indicate that the host identified by the first IP address accesses the network by using the second gateway; and the first gateway writes an address of the second gateway into the forwarding table as a next hop address of the first IP address.
