這有個(gè)很奇怪的問(wèn)題,在R1上:

 Sum-Asbr 93.3.3.3       92.2.2.2         1563 28   80000001   1562

R2居然通告R3是ASBR,并且產(chǎn)生一條LSA4

[R1]dis ospf lsdb asbr

        OSPF Process 10 with Router ID91.1.1.1

                        Area: 0.0.0.0

 seq#     : 80000001

 chksum   : 0xe65

 Tos 0 metric: 1562

重啟OSPF進(jìn)程也一樣。也就是說(shuō),在華為路由器上,沒有LSA5也可以產(chǎn)生LSA4,后來(lái)練習(xí)完下面的vlink-peer再返回來(lái)做這個(gè)練習(xí),發(fā)現(xiàn)又正常了,R1上沒有LSA4,只有LSA3的路由,這個(gè)可能是緩存當(dāng)時(shí)沒有得到徹底的清除所導(dǎo)致

利用tunnel的方法,可以看到R1上收到的Area2的路由是以LSA3類形式存在的,比用第一種雙向多進(jìn)程重分布要好點(diǎn)

比較tunnel和vlink-peer,發(fā)現(xiàn)兩者都得到LSA3類路由,而且兩者都是p2p鏈路

vlink仍然是p2p類型:

[R2]dis ospf vlink

        OSPF Process 10 with Router ID92.2.2.2

                Virtual Links

 Virtual-link Neighbor-id -> 93.3.3.3, Neighbor-State: Full

 Interface: 23.1.1.2 (Serial0/0/1)

 Cost: 1562 State: P-2-P Type: Virtual

 Transit Area: 0.0.0.1

 Timers: Hello 10 , Dead 40 , Retransmit 5 ,Transmit Delay 1

tunnel也是p2p類型:

[R3]dis ospf int all

        OSPF Process 10 with Router ID93.3.3.3

                Interfaces

 Area: 0.0.0.0         (MPLS TE not enabled)

 Interface: 100.1.1.3 (Tunnel0/0/0)--> 100.1.1.2

 Cost: 1562   State: P-2-P    Type: P2P      MTU: 1500

 Timers: Hello 10 , Dead 40 , Poll 120 , Retransmit 5 , Transmit Delay 1

這兩者其實(shí)很像

和vlink一起的考試經(jīng)常是說(shuō)要在Area0上做區(qū)域認(rèn)證,那么請(qǐng)把vlink認(rèn)證補(bǔ)全,這種問(wèn)題其實(shí)在華為路由器上特別簡(jiǎn)單,只要在vlink-peer后面接著做相同的認(rèn)證就可以了

補(bǔ)全不規(guī)則區(qū)域:

 以下略。

應(yīng)該說(shuō)R4關(guān)于1.1.1.1/32的路由從R2、R3收到,有兩條做負(fù)載均衡才對(duì),但這只有一條。

真實(shí)的情況如下:

[R4]dis ospf lsdb

        OSPF Process 10 with Router ID 94.4.4.4

                Link State Database

                        Area: 0.0.0.0

                        Area: 0.0.0.2

 Type     LinkState ID   AdvRouter         Age Len  Sequence  Metric

Sum-Net  1.1.1.1        94.4.4.4          940 28   80000002   3124

 Sum-Net  1.1.1.1        93.3.3.3         1275 28   80000001   1562

                        Area: 0.0.0.3

 Type     LinkState ID   AdvRouter         Age Len  Sequence  Metric

Sum-Net  1.1.1.1        92.2.2.2          960 28   80000002   1562

可以看到,R4收到Area 2的兩條,Area 3的一條關(guān)于1.1.1.1/32主機(jī)路由,由于Area 2中同一條LSA比較metric,最后兩條是Area 2和Area 3的路由,它們的metric一樣,只不過(guò)所在Area區(qū)域不同,由于OSPF規(guī)定這樣的等價(jià)路由比較Area區(qū)域號(hào),哪個(gè)大用哪個(gè),所以ospf把92.2.2.2的1.1.1.1路由放入路由表中(區(qū)域零例外,因?yàn)閰^(qū)域零最?。?/p>
