Specific implementation mode
The purpose of the present invention is syntople and do not influence net for being currently based in the ospf network environment of IPv6 to establish The contradiction of network topology, it is proposed that the passive acquisition method and system of the ospf network routing iinformation based on IPV6, so as to network Situation carries out real time monitoring analysis, and the acquisition solved in existing technologies is not comprehensive, is impacted to network, and acquisition real-time is poor The problems such as.
It is the specific steps of the present invention below, as follows:
The passive acquisition technique of OSPFv3 routing iinformations of single Autonomous Domain in IPV6 networks:
In OSPFv3 networks, the stage of routers exchange routing iinformation includes two:Router establishes Routing Protocol neighbour It is established after routing protocol neighbor relationship with router before connecing relationship.
It establishes before syntople, every router elects DR by using hello packet, according to respective priority And establish syntople between its neighbours.Every router is to each neighbours' transmission link state advertisement (LSA), Mei Gelin Residence will forward these LSA (flooding) to its neighbours successively after receiving LSA.Every router will preserve one in the database Part its backup of LSA for being received, all-router safeguard a identical database, referred to as LSDB.Under normal circumstances, two The process that router establishes syntople is as shown in Figure 1.
It establishes after syntople, is established after syntople between router, do not retransmit DD (Database mutually Description data specifying-informations message) etc. information, only send Hello and maintain necessary syntople, when certain routing After device receives LSA, the information of the LSA is directly sent to neighbor router.
In order to realize the purpose of passive acquisition OSPFv3 network route informations, uses three kinds of measures and improve above two Process, as follows:
The priority of collecting device is set as minimum, in ospf network, the router for establishing syntople will be according to setting Standby priority elects DR (Designated Router Designed Routers) to flood the link-state information in this domain, as acquisition Equipment to avoid with Autonomous Domain in router establish full adjacency when be elected as DR, increase the burden of collecting device, The real-time of message acquisition is influenced, therefore the priority of collecting device is set as minimum, is not involved in the election of DR;
The Data Description (DD) packet exchanged with neighbor router is sky, before collecting device and neighbor router establish syntople, is needed LSA database description exchanges are carried out, collecting device is not to the heads LSA corresponding to neighbor router declaration collecting device at this time Information sends empty Data Description (DD) packet, such neighbor router will not ask any LSA information to collecting device, to realize quilt The purpose of dynamic acquisition routing iinformation, and neighbor router is entered with being all transmitted for LSA information between router Full adjacent state;
Router does not send LSU (Link State Update Link State Update Packets) after establishing syntople, when After routing iinformation collecting device enters full adjacent state with neighbor router, the LSA reports of neighbor router transmission can be got Text, and collecting device will not send the LSA messages of the syntople into network, to realize the purpose passively acquired.By It is not present in region in the LSA information of routing iinformation acquisition probe, therefore routing iinformation acquisition probe and neighbor router Between an only unidirectional side exist, and unidirectionally side can't be used for router-level topology in ospf protocol specification, realize passive type The requirement of monitoring.
More Autonomous Domain OSPFv3 network route information acquisition techniques in IPV6 networks:
The purpose of more Autonomous Domain OSPFv3 network route informations acquisitions can be adopted by a routing iinformation collecting device Collecting OSPFv3 network route informations in multiple Autonomous Domains, this kind of information collection mode has many good qualities, such as:It can make equipment Deployment way it is more flexible, while realizing making full use of for equipment.
OSPFv3 is intra-area routes agreement, and message information only floods in this Autonomous Domain, therefore does not have AS Number words Section cannot be distinguished No. AS (Autonomous System autonomous systems).Some router in collecting device and an Autonomous Domain A full adjacency is established, the message information of the Autonomous Domain is obtained.When there are multiple Autonomous Domains, collecting device need with it is every Router in a Autonomous Domain establishes full adjacency.In order to distinguish the message of different Autonomous Domains, need that header will be acquired Stamp a label, the tag identifier IP address of routing iinformation sender passes through that this IP address is corresponding with No. AS closes System determines No. AS where collected message.
Meanwhile there are the LSA information of different Autonomous Domains in the LSDB of collecting device, when establishing syntople, it is necessary to protect It is sky to demonstrate,prove the LSA header informations that database description switching phase is sent, and the priority of collecting device is reduced to minimum, it is ensured that OSPF messages in different Autonomous Domains keep independent, cannot influence each other.
The present invention also proposes the passive acquisition system of the ospf network routing iinformation based on IPv6, including:
Every router elects DR by hello packet, according to the respective priority of router, and with the neighbours road of DR By establishing syntople between device, every router is to each neighbor router transmission link state advertisement information, each neighbours Router is logical to neighbours' conversion link state of each neighbor router successively after receiving link state notification information Accuse information;
Single Autonomous Domain ospf network obtains information module, for establishing the syntople in IPv6 networks between router, Hello packet is only sent between middle router and maintains necessary syntople, when certain router receives Link State Notification After information, directly the link state notification information is sent to neighbor router;
More Autonomous Domain ospf networks obtain information module, if being more Autonomous Domain OSPF nets for ospf network in IPv6 networks Network, collecting device establishes full adjacency with the router in each Autonomous Domain, and a label is arranged in the head for acquiring message, The IP address that the sender of message is acquired described in the tag identifier, is determined with No. AS correspondence by the IP address and is adopted No. AS where the message collected.
Every router preserves the backup for the link state notification information that this router is received, institute in the database There is router to safeguard a identical database.
The list Autonomous Domain ospf network obtains information module and further includes:The priority of collecting device is set as minimum;Often The Data Description (DD) packet that a router is exchanged with neighbor router is sky;Router stops sending LSU after establishing syntople.
When more Autonomous Domain ospf network acquisition information Steps further include the syntople between establishing router, database It is sky to describe the link state notification information that switching phase is sent, and the priority of collecting device is reduced to minimum.
It is one embodiment of the invention below, as follows:
As shown in Fig. 2, in the ospf network of the mono- AREA of more AS, a collecting device is disposed in network, start BGP and One or more normal router in ospf protocol, with network establishes BGP or ospf adjacency relationship, ensures this router With the connectivity of other routers, the collecting work of routing data can be proceeded by.
