Description
Technical field
The present invention relates to route technology, particularly many topologys are definite method and apparatus of Att mark down.
Background technology
At present; In intermediate system-intermediate system (ISIS); Router mainly is divided three classes, and is respectively two layers of (level-2) router and the border router (being also referred to as level-1,2 routers) in the zone on one deck (level-1) router in the zone, the backbone network.Wherein, the level-1 router can not link to each other with the router in other zones, and the level-2 router connects different zones, and border router links to each other with level-2 router on the backbone network.
Support at ISIS under the situation of how topological route (MTR) characteristic that the area configurations of level-1 router and border router issue is not distinguish topology, this just possibly cause following two problems:
1, some zone generates unnecessary default route:
In networking shown in Figure 1, have three zones, be respectively zone 1 to zone 3, wherein, zone 1 is IPV4 with the topology in zone 2, and the topology in zone 3 is IPV6, and the area configurations of each router is as shown in Figure 1 in the zone.If the router R on the backbone network (being essentially the level-2 router) does not support the IPV6 topology, support among Fig. 1 that then the zone 3 of IPV6 topology is equivalent to an isolated island, therefore, need in zone 3, not generate the default route information of going out.But; For zone 3; Its border router F is learning two layers of label translation-protocol information (level-2LSP that border router B and border router C send; Wherein comprised area configurations 04.44 and area configurations 04.54 respectively) time; Relatively whether this area configurations of learning exists in the area configurations of the level-1 router issue of hanging down, if generation is changed to 0 Att mark; If, do not generate the Att mark of set based on this area configurations; Afterwards, the Att mark that generates is sent to down the level-1 router of hanging.In Fig. 1; The level-1 router that border router F hangs down is router E, and the area configurations of its issue does not comprise the above-mentioned area configurations of learning 04.44 and 04.54, therefore; Border router will generate the Att mark of set respectively according to these two area configurations, and sends to router E.Receive the Att mark of this set as router E after, will generate the default route that points to border router F according to this Att mark.
Because the router R on the backbone network does not support the IPV6 topology, and the topology in other two zones is IPV4, therefore, support the zone 3 of IPV6 topology to there is no need to generate the default route that points to border router F among Fig. 1 at all.Therefore, the default route that can obtain above-mentioned generation is unnecessary default route, and this necessary default route can cause the data leak of zone in 3 to backbone network.
2, some zone does not generate necessary default route:
In networking shown in Figure 2, have three zones, be respectively zone 1 to zone 3, wherein, the topology in zone 1 and zone 3 is the IPV6 topology, and the topology in zone 2 is IPV4.Area configurations on each router is as shown in Figure 2, and wherein, the router D among Fig. 2 has two area configurations, is respectively 04.54 and 06.33.In Fig. 2, the router R on the backbone network supports dual stack IPV4 and IPV6, in order to make zone 1 and zone 3 networkings, need in zone 3, generate the default route information of going out.But, when border router C learns the area configurations 06.33 of border router B issue, because the level-1 router that this border router is hung down has two; Be respectively router D and E; And, comprise the area configurations 06.33 that border router is issued in the area configurations of this router D issue, therefore; Border router C can be changed to 0 Att mark according to this area configurations 06.33 generation, sends to router D and E afterwards.When router E receives this Att mark, just can not generate the default route that points to IPv6 Area Border Router C.
Because the zone 1 and 3 among Fig. 2 all is the IPV6 topology; And the router R on the backbone network supports dual stack IPV4 and IPV6; Therefore, in order to make zone 1 and zone 3 networkings, need in zone 3, generate the default route information of going out; And it is above-mentioned owing to the router in the different topology has been issued identical area configurations and caused border router can not generate correct Att mark; Make router E can not generate the default route that points to IPv6 Area Border Router C, caused the far-end IP v6 topology in the IPv6 zone can not form the networking state, cause unnecessary service disconnection.
Find out from top description; Why produce this two problems; The area configurations that mainly is the issue of level-1 router and border router is not distinguished topology and is caused, and in order to address this problem, a kind of regional address issue that can distinguish topology is that current demanding urgently needs.
Summary of the invention

Embodiment
In order to make the object of the invention, technical scheme and advantage clearer, describe the present invention below in conjunction with accompanying drawing and specific embodiment.
The method that the embodiment of the invention provides mainly comprises flow process shown in Figure 3:
In step 301; The corresponding relation of other border router issues; And the corresponding relation of level-1 router issue all is to be carried in the V field of TLV field to issue, and the T field in this TLV field is different with the T field that has the TLV field that is used for issuing area configurations now.Usually, the existing T field value that is used for issuing the TLV field of area configurations is 0 or 1, and therefore, desirable other values of T field in the TLV field that the embodiment of the invention adopts are such as 255 etc.
As for the corresponding relation that how to utilize between TLV field issue area configurations and the topology sign, specifically can be referring to shown in Figure 4.In TLV field shown in Figure 4, the V field is used for bearing area configuration and topology sign.Wherein, the length of this area configurations accessible region domain addresses and regional address representes that the available MTID of topology sign representes.
In TLV field shown in Figure 4, the L field is used to represent V field loaded information length.Its size generally is no more than 255 bytes.
Particularly, step 303 is: after generating the 2nd Att mark, the 2nd Att mark is sent to down the level-1 router of hanging, after the level-1 router receives the 2nd Att mark, do not generate the default route that points to first border router.Here, the 2nd Att mark can be: be changed to 0 Att mark.
After step 305, level-1 router receive a topology sign and an Att mark, judge and self whether support and topology to identify, if generate the default route that points to first border router according to a said Att mark; Otherwise the topology that abandons this reception identifies and an Att mark.
Here, an Att is labeled as non-0 Att mark.
So far, accomplish flow process shown in Figure 3.
For making the embodiment of the invention clearer, be that example is described with networking illustrated in figures 1 and 2 below.
In Fig. 1; Border router F is at area configurations 04.44 that receives router B issue and the corresponding relation of topology sign between 1 (being used to represent IPV4 structure); And/or during the corresponding relation between the area configurations 04.54 of router C issue and the topology sign 2 (being used to represent IPV4 another kind structure); To each corresponding relation that receives, judge the level-1 router of self hanging down is whether to have this corresponding relation in the corresponding relation of router E issue.Because the corresponding relation of router E issue is area configurations 06.33 and the corresponding relation of topology sign between 3 (being used to represent IPV6 structure), therefore, this judged result is not.For not the time, border router F will generate an Att mark such as 04.54 according to the area configurations in this corresponding relation, and the sign of the topology in this corresponding relation is sent to router E such as topology sign 2 and first mark that generates in this judged result.After router E receives topology sign the 2 and the one Att mark; Because router E supports IPV6; And should topology the structure of sign 2 expression IPV4, do not support should topology sign 2 for router E obviously, therefore; Can not generate the default route that points to border router F, but directly abandon topology sign the 2 and the one Att mark of this reception according to an Att mark.And in fact; Because the router R among Fig. 1 on the backbone network does not support the IPV6 topology; And the topology in zone 1 and 2 is supported IPV4, therefore; Support the zone 3 of IPV6 topology to be equivalent to an isolated island among Fig. 1, the router E in this zone 3 is that to there is no need to generate the default route that points to border router F be correct.Through the method that the embodiment of the invention provides, can guarantee can not generate unnecessary default route.
To Fig. 2; The corresponding relation of border router C between area configurations 06.33 that receives border router B issue and topology sign I (being used to identify a kind of structure of IPV6 topology); Will be directed against this corresponding relation, judge router D and router E the issue corresponding relation in whether have this corresponding relation.Because being area configurations 04.54, the corresponding relation of router D issue (is used to represent other structures of IPV4 topology with topology sign 3; This topology sign also can be above-mentioned topology sign 1 or 2) between corresponding relation; And the corresponding relation between area configurations 06.33 and the topology sign 3; The corresponding relation of router E issue is that area configurations 06.77 identifies the corresponding relation between the II (be used to represent the another kind of structure of IPV6, also can be above-mentioned topology sign I) with topology, and it does not comprise the corresponding relation between above-mentioned area configurations 06.33 and the topology sign I; Therefore, above-mentioned judged result is for denying.Afterwards, border router C will generate an Att mark according to the area configurations in this corresponding relation 06.33, and first mark of sign I of the topology in this corresponding relation and generation is sent to router E and D; After router E receives,, and should topology identify a kind of structure that I also representes this IPV6 because router E supports IPV6; Therefore; Exist this router E to support the possibility of topology sign I, when supporting, generate the default route that points to first border router according to an Att mark; Otherwise the topology that abandons this reception identifies an I and an Att mark, and this can solve prior art because different topology can not generate the problem of necessary default route but area configurations is identical.And after router D receives a topology sign I and an Att mark; Because router D supports IPV4, and should topology identify the structure that I representes IPV6, router D does not support and should topology identify I obviously; Therefore; Can not generate the default route that points to border router C according to an Att mark, but directly abandon the topology sign I and an Att mark of this reception, this can guarantee that zone 2 can not generate unnecessary default route.
So far, specific embodiment provided by the invention is accomplished description.
In above-mentioned flow process; Step 301 is receiving other border routers or when the area configurations of the level-1 router issue of hanging down and the corresponding relation between the topology sign at first border router; Also can further comprise following operation: judge the topology sign of self whether supporting in this corresponding relation; If just carry out following step 302 to this corresponding relation; Otherwise, abandon this corresponding relation.
Consider the flexibility of the embodiment of the invention; The router that in the embodiment of the invention is not All Ranges all can be issued the corresponding relation between area configurations and the topology sign, but is only enabling just can to issue the corresponding relation between area configurations and the topology sign after the topology issue characteristic provided by the invention; And to the router that does not enable this topology issue characteristic, then can handle according to existing method, promptly only issue area configurations.Certainly, as a kind of expansion of the embodiment of the invention, the embodiment of the invention also can be given tacit consent to all-router and enable topology issue characteristic provided by the invention.The concrete condition concrete analysis does not specifically limit here.
Need to prove; If in step 301; When if first border router receives the area configurations of the router issue that does not enable topology issue characteristic, the corresponding relation of giving tacit consent to this router issue is the area configurations of this issue and the corresponding relation between the default value.Such as, if when receiving the area configurations of the border router issue that does not enable topology issue characteristic, the corresponding relation of then giving tacit consent to this border router issue is the area configurations of this issue and the corresponding relation between the default value.Afterwards, to this corresponding relation, execution in step 302.
In above-mentioned flow process, can realize through following step when step 302 specifically realizes: each topology of collecting other border routers issues identifies corresponding area configurations, and leaves in the table 1; Collect the corresponding area configurations of each topology sign of level-1 router issue, and leave in the table 2; Each topology sign in the table 1 should topology identify if also exist in the table 2, then in table 1, confirms the corresponding area configurations of this topology sign; To each area configurations; Should topology identify in the corresponding area configurations if this area configurations also exists in the table 2, then execution in step 303, otherwise; Execution in step 304 promptly generates the operation of an Att mark according to this area configurations; And if do not exist in the table 2 should topology sign, direct execution in step 304 then is promptly according to the operation that should each corresponding area configurations of topology sign in the table 2 generates an Att mark.
