Embodiment Construction

[0107] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0108] The basic train of thought of the present invention is to utilize the value of Address Family Identifier (Address FamilyIdentifier, be called for short AFI) in MP-BGP, propose a kind of new NLRI configuration method, to realize MP-BGP automatic route E.164, E.214, SP number function. The NLRI configuration includes MP_REACH_NLRI configuration and MP_UNREACH_NLRI configuration. The configuration of MP_REACH_NLRI involved in the present invention requires corresponding modifications to the existing MP_REACH_NLRI routing attributes; the configuration of MP_UNREACH_NLRI involved in the present invention requires corresponding modifications to the existing MP_UNREACH_NLRI routing attributes. The following describes the MP_REACH_NLRI routing attribute, MP_UNREACH_NLRI routing attribute, and NLRL Encoding in the MP-BG...

Abstract

The invention relates to a method for routing numbers automatically, a method for updating, a method for cancellation, a router and equipment, wherein, the method for routing numbers automatically comprises that: the numbers which wait to be distributed are converted to number routing information, and the number routing information is added in the dynamic routing protocol; according to the number routing information, the dynamic routing protocol message is generated; the dynamic routing protocol message is transmitted by IP network, and the numbers are distributed by the dynamic routing protocol message and the IP network. In the method of the invention, by expanding the existing MP-BGP protocol, automatic routing of the numbers of E.164, E.214, SP, and the like, is supported, network optimization structure is realized, and efficiency is improved.

Description

technical field [0001] The invention belongs to the field of computer networks and relates to an extended MP-BGP, in particular to an automatic number routing method and a router based on the extended MP-BGP protocol in a communication network. Background technique [0002] The traditional Border Gateway Protocol (BGP for short) defined in the standard RFC1771, that is, BGP-4, can only manage the routing information of the network layer protocol IPv4. For other network layer protocols, such as IPv6, IPX, L3VPN protocols, etc., It is subject to certain restrictions when spreading across autonomous systems. [0003] (1) Extension to BGP-4 [0004] As an extension to BGP-4, IETF released the standard RFC2858 (MultiprotocolExtensions for BGP-4, multi-protocol extension of BGP-4), RFC 4760, which defines the MultiProtocol-BGP (MultiProtocol-BGP, referred to as MP -BGP), the MP-BGP can support multiple network protocols, such as IPv6, IPX, L3VPN, etc. MP-BGP extensions are back...
