Problems solved by technology

[0037] To sum up, when the MTI address is introduced into the private network routing table, if the MTI address overlaps with the private network address, it will affect the multicast service and MPLS L3VPN service
For example, when a company switches operators, if the original mobile operator, multicast VPN and MPLS L3VPN do not have address overlap, but needs to switch operators and transfer to China Unicom, the above-mentioned address overlap problem will occur. Conflict between multicast and MPLS L3VPN services

Embodiment Construction

[0100] When both multicast VPN and MPLS L3VPN services exist in the networking environment, if the MTI interface address of the multicast VPN service overlaps with the private network address of the MPLS L3VPN, the corresponding MTI interface address in the multicast VPN Public network routes will be leaked to the private network, thereby affecting both multicast VPN and MPLS L3VPN services.

[0101] In view of the above problems, in the present invention, by maintaining the corresponding MT identification for the MTI interface address, when the MTI interface address needs to be used, it can be clearly known that the address with the MT identification is the MTI interface address, so that the MTI interface address will not be used in the multicast VPN. The public network route corresponding to the MTI interface address is leaked to the private network, so that the multicast VPN and MPLS L3VPN services do not affect each other.

[0102] Based on the above ideas, the present inv...

Abstract

The invention discloses a processing method of data, comprising the following steps: receiving a message by a PE device and learning that the message is a message coming from a MTI interface or coming from a private network; if the message comes from the MTI interface, the PE device judges whether to maintain the neighbourship according to the message based on the MT identification corresponding the address of the MTI interface, if necessary, the neighbourship is maintained. The MPLS L3VPN business and the multicast VPN business are not influenced mutually in the method of the invention.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a data processing method and equipment. Background technique [0002] (1) Multicast VPN (Virtual Private Network, Virtual Private Network). [0003] The multicast VPN is a technology based on an MPLS (Multiprotocol Label Switching, multi-protocol label switching) L3VPN network to realize multicast transmission. Among them, MPLS L3VPN is a VPN realized based on BGP (Border Gateway Protocol, Border Gateway Protocol) and MPLS extension technology. It is composed of the backbone network of the operator and each Site (site) of the user. They are isolated from each other and need to use the backbone network to achieve intercommunication. In MPLS L3VPN, VPN can be regarded as a group of policies, which control the connection between various sites. [0004] Such as figure 1 As shown, it is a typical application of MPLS L3VPN. exist figure 1 Among them, Site 1, Site 3, ...
