Abstract

The invention provides a route notification method and device, the method is applied to first network equipment, the first network equipment is located in a DRNI active-active gateway network, the DRNI active-active gateway network also comprises second network equipment, the first network equipment and the second network equipment respectively comprise a first interface and a second interface, wherein the first interface and the second interface are three-layer interfaces and are configured with the same IP address. The method comprises the following steps: receiving a first RA message sent by a second network device through an IPL link through an IPP port included in a first network device, the first RA message comprising a first life cycle field; and when the value of the first lifecycle field is the first value, sending a second RA message to a third network device through an aggregation port included in the first network device, the second RA message comprising the IP address of the first interface and the second lifecycle field, so that the third network device forwards the second RA message to an accessed host.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a route notification method and device. Background technique [0002] Today, with the increasingly widespread application of IPv6 networks, the route notification message issued by the gateway has become a necessary configuration in the IPv6 network. In the stateful address allocation network, the host obtains the corresponding IPv6 address through the allocation of the DHCPv6 server. In addition to the local static configuration, the host only obtains the gateway IP address through the Router Advertise (English: Router Advertise, referred to as: RA) message; In a stateless address allocation network, the host also obtains the IPv6 address prefix, gateway IP address, and other required parameters through RA messages. [0003] When the gateway in the network starts up, the gateway quickly sends an RA message; when the interface of the gateway goes down or the...
