配置OSPF動(dòng)態(tài)路由協(xié)議，在接口配置認(rèn)證，保證更新安全

重發(fā)布

配置完RIP動(dòng)態(tài)路由協(xié)議與OSPF動(dòng)態(tài)路由協(xié)議之后，雙方協(xié)議并沒(méi)有對(duì)方的路由條目，所以要正常通信就要進(jìn)行雙向重發(fā)布操作

注：先在R7上重發(fā)布環(huán)回，然后在R2、R3上重發(fā)布

?環(huán)路

做完多點(diǎn)雙向重發(fā)布之后，要保證R2、R3?上路由表不發(fā)生變化，否則就會(huì)出現(xiàn)環(huán)路

?

R2的路由表上有一些問(wèn)題：R2去R3的環(huán)回有兩條路徑（1）走左邊RIP，路由條目掩碼是25位，（2）走右邊OSPF，路由條目掩碼是32位（華為模擬器認(rèn)為環(huán)回地址是32位掩碼）

修改方案：（1）把環(huán)回接口地址掩碼修改為32位（2）修改環(huán)回接口類(lèi)型

#第一種方案
[r3]interface LoopBack 0
[r3-LoopBack0]undo ip address 30.1.1.129 25
[r3-LoopBack0]ip address 30.1.1.129 32
[r3-LoopBack0]q
[r3]#第二種方案
[r3]interface LoopBack 0
[r3-LoopBack0]ospf network-type broadcast 
[r3-LoopBack0]q
[r3]

修改成功，解決問(wèn)題。?

?

????????此時(shí)R3上的路由已經(jīng)出現(xiàn)問(wèn)題，R3認(rèn)為去R7的環(huán)回要走RIP，然后繞到R2（這里是因?yàn)镽7的環(huán)回是重發(fā)布進(jìn)OSPF的，起初R3加表的重發(fā)布的R7環(huán)回，優(yōu)先級(jí)為150，但是經(jīng)過(guò)R2重發(fā)布進(jìn)RIP，經(jīng)過(guò)R1通過(guò)RIP的學(xué)習(xí)，然后再傳給R3，這條經(jīng)RIP學(xué)習(xí)到的路由，優(yōu)先級(jí)為100，經(jīng)過(guò)對(duì)比，R3就會(huì)將從RIP學(xué)到的R7環(huán)回加入路由表中，這樣就會(huì)導(dǎo)致選路不佳，并且有可能出現(xiàn)環(huán)路）

????????

可以用wireshark來(lái)抓包查看，這個(gè)ICMP（ping70.1.1.129）包在R1~R4之間傳遞，每次TTL值減4。此時(shí)已經(jīng)成功出現(xiàn)環(huán)路，但是由于timeout時(shí)間只有2s，并且有ttl值限制，并未顯現(xiàn)出來(lái)?

解決方案：路由策略修改優(yōu)先級(jí)

[r3]ip ip-prefix a permit 70.1.1.128 25[r3]route-policy q permit node 10
Info: New Sequence of this List.
[r3-route-policy]if-match ip-prefix a

[r3-route-policy]q[r3]rip 1
[r3-rip-1]preference route-policy q
[r3-rip-1]q
[r3]

最后是選路問(wèn)題

1、R1去R2（包括環(huán)回）可以走兩條路徑，但并沒(méi)有負(fù)載均衡

解決方案：在R2上做路由策略，修改開(kāi)銷(xiāo)值（開(kāi)銷(xiāo)值加2）
AR2：

[r2]ip ip-prefix qq permit 30.1.1.128 25
[r2]ip ip-prefix qq permit 40.1.1.0 30
[r2]interface GigabitEthernet 0/0/0

[r2-GigabitEthernet0/0/0]q                          
[r2]

2、R1去R3（包括環(huán)回）也可以走兩條路徑，但并沒(méi)有負(fù)載均衡，

解決方案：在R2上做路由策略，修改開(kāi)銷(xiāo)值（開(kāi)銷(xiāo)值加2）

AR3：

[r3]ip ip-prefix qq permit 30.1.1.0 30     
[r3]interface GigabitEthernet 0/0/0
[r3-GigabitEthernet0/0/0]rip metricout ip-prefix qq 2
[r3-GigabitEthernet0/0/0]q
[r3]

3、R4也是一樣，去R2（包括環(huán)回）可以走兩條路徑，但并沒(méi)有負(fù)載均衡

解決方案：在R2上做路由策略，修改類(lèi)型（重發(fā)布為類(lèi)型2，修改為類(lèi)型1）

AR2：

#匹配流量
[r2]ip ip-prefix qqq permit 10.1.1.0 30
[r2]ip ip-prefix qqq permit 20.1.1.128 25#配置策略
[r2]route-policy z permit node 10

[r2]ospf 1
[r2-ospf-1]import-route rip 1 route-policy z
[r2-ospf-1]q
[r2]

4、R4也是一樣，去R3（包括環(huán)回）可以走兩條路徑，但并沒(méi)有負(fù)載均衡

解決方案：在R2上做路由策略，修改類(lèi)型即可

AR3：

#捕捉流量
[r3]ip ip-prefix z permit 20.1.1.0 30#配置策略
[r3]route-policy z permit node 10
Info: New Sequence of this List.
[r3-route-policy]if-match ip-prefix z
[r3-route-policy]apply cost-type type-1
[r3-route-policy]q#建立空表放過(guò)流量

[r3]ospf 1
[r3-ospf-1]import-route rip 1 route-policy z
[r3-ospf-1]q
[r3]

R1和R7的環(huán)回可以正常通信 ，實(shí)驗(yàn)到此為止，環(huán)路和選路不佳解決，要求也是全部完成。
