Problems solved by technology

This solution obviously has the disadvantages similar to solution 1. When the NAT-PT IPv6 prefix changes, all the static routes configured above pointing to the NAT-PT IPv6 prefix network segment must be modified.
At the same time, this solution has other disadvantages. For example, if the above-mentioned static route is only configured on one or a few devices, it will not be conducive to the balanced distribution of NAT-PT traffic, and when a single point of failure occurs in the network, it may even cause Unable to access the IPv4 network; if the above static routes are configured on a large number of devices in the IPv6 network, it will obviously greatly increase the workload of configuration and maintenance

Embodiment Construction

[0034] The present invention provides a routing information publishing method and a NAT-PT gateway device. The NAT-PT gateway device detects its own NAT-PT IPv6 prefix and publishes the routing information of the detected NAT-PT IPv6 prefix to The IPv6 network side enables other routing devices in the IPv6 network to obtain the route corresponding to the NAT-PT IPv6 prefix. Hereinafter, the present invention will be described in detail through specific embodiments with reference to the accompanying drawings.

[0035] The routing information publishing method according to the embodiment of the present invention is used to publish the route corresponding to the NAT-PT IPv6 prefix to the routing table on the IPv6 network side, as shown in FIG. 2, including the following steps:

[0036] Step 21: The NAT-PT gateway device detects its own NAT-PT IPv6 prefix.

[0037] Here, the NAT-PT IPv6 prefix on the NAT-PT gateway device is usually configured by the user. Therefore, the above detection...

Abstract

The provided route message releasing method comprises: A. the NAT-PT gateway device detects itself NAT-PT IPv6 prefix to generate and release the route message; and B. the other route devices in IPv6 network obtain the route according to received NAT-PT IPv6 prefix. This invention saves manual configuring static route, reduces work load, and frees to modify configuration message after changing the NAT-PT IPv6 prefix.

Description

Technical field [0001] The invention relates to the field of data communication, in particular to a method for issuing routing information and a network address translation-protocol translation (NAT-PT, Network Address Transl ation-Protocol Translation) gateway device. Background technique [0002] The routing protocol is used to build and maintain routing tables. The router establishes and maintains its routing table by passing routing protocol information between routers. At present, the mainstream Internet Protocol version 6 (IPv6, Internet Protocol version 6) routing protocol includes Open Shortest Path First version 3 (OSPFv3, Open Shortest Path First version 3), intermediate system-intermediate system (IS-IS, intermediate system-to -intermediate system), a new generation of Routing Information Protocol (RIPng, Routing Information Protocol, next generation) and Border Gateway Protocol version 4 extensions (BGP4+, Border Gateway Protocol version4plus), etc. Among them, OSPF...
