Embodiment Construction

[0025] The specific implementation manners of a route advertisement method and network equipment provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] A route notification method provided by an embodiment of the present invention, such as figure 2 shown, including:

[0027] S201. The first network device running the second version of the Routing Information Protocol RIPv2 determines the Routing Information Protocol version run by its neighbor device;

[0028] S202. When the first network device notifies a supernet route to a neighboring device running the first version of RIPv1, split the supernet route into routes of continuous classful networks included in the supernet;

[0029] S203. Advertise the route of the split continuous classful network to the neighbor device running RIPv1.

[0030] The route advertisement method provided by the embodiment of the present invention will be described in detail bel...

Abstract

The invention discloses a route advertising method and network equipment, wherein the method comprises the following steps: determining route information protocol versions run by all neighborhood equipment by first network equipment running a second version RIPv2 (Routing Information Protocol version 2) of a route information protocol; and splitting a hypernet route into continuous routes of classful networks contained in a hypernet and advertising the split continuous routes of the classful networks to the neighborhood equipment running RIPv1 (Routing Information Protocol version 1) through the first network equipment when the first network equipment advertises the hypenet routes to the neighborhood equipment running the RIPv1 (Routing Information Protocol version 1) of the route information protocol. The invention can ensure that equipment running the RIPv1 (Routing Information Protocol version 1) can correctly learn all continuous routes of the classful networks contained in the hypernet in a network running the RIPv1 protocol and the RIPv2 protocol, thereby avoiding the problem of route black hole.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to a route notification method and network equipment. Background technique [0002] When the Internet was originally designed, in order to facilitate addressing and construct the network hierarchically, each IP address includes two identification codes (ID), namely, the network ID and the host ID. All hosts on the same physical network use the same network ID, and a host on the network (including workstations, servers, and routers on the network) has a host ID corresponding to it. IP addresses are divided into 5 types according to different network IDs, Class A addresses, Class B addresses, Class C addresses, Class D addresses, and Class E addresses. code. As shown in Table 1 below: [0003] Table 1 [0004] class prefix bit scope prefix length default subnet mask Class A 0 0.0.0.0～127.255.255.255 / 8 255.0.0.0 ...
