第二步:配置OSPF
area1中,r1,r2汇总宣告,r3取相同去不同宣告。
R1

[R6-ospf-1]area 2
[R6-ospf-1-area-0.0.0.2]network 172.16.65.1 0.0.0.0
R7
[R7]ospf 1 router-id 7.7.7.7
[R7-ospf-1]area 0
[R7-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.7.255
[R7-ospf-1-area-0.0.0.0]q
[R7-ospf-1]area 3

[R8]ospf 1 router-id 8.8.8.8
[R8-ospf-1]area 3
[R8-ospf-1-area-0.0.0.3]network 172.16.0.0 0.0.255.255
R9
[R9]ospf 1 router-id 9.9.9.9
[R9-ospf-1]area 3
[R9-ospf-1-area-0.0.0.3]network 172.16.97.10 0.0.0.0
[R9-ospf-1-area-0.0.0.3]q
[R9-ospf-1]q
[R9]ospf 2 router-id 9.9.9.9
[R9-ospf-2]area 4
[R9-ospf-2-area-0.0.0.4]network 172.16.128.0 0.0.3.255
R10
[R10]ospf 1 router-id 10.10.10.10

[R10-ospf-1-area-0.0.0.4]network 172.16.0.0 0.0.255.255

[R12]rip 1
[R12-rip-1]version 2
[R12-rip-1]network 172.16.0.0 --- 汇总宣告
第三步:由于P2P类型是无法与其他路由之间建立邻居关系,则需更改MGRE类型 --- P2MP类型 。
R3
[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]ospf network-type p2m
R5
[R5]int Tunnel 0/0/0
[R5-Tunnel0/0/0]ospf network-type p2mp
R6
[R6]int Tunnel 0/0/0
[R6-Tunnel0/0/0]ospf network-type p2mp
R7
[R7]int Tunnel 0/0/0
[R7-Tunnel0/0/0]ospf network-type p2mp
area4区域和rip区域间缺失的路由信息,需要我们手工使用重发布的方式导入rip路由和area4的路由信息
[R12]ospf 1
[R12-ospf-1]import-route rip 1
[R9]ospf 1
[R9-ospf-1]import-route ospf 2
R10里面会发现没有其他的路由信息,这时我们可以下发一条缺省路由指向我们的R9
[R9]ospf 2
[R9-ospf-2]default-route-advertise
第四步:为了减少LSA的更新量,我们需要做汇总与特殊区域
注意:在汇总时为了避免环路我们还需要配置空接口路由。
R3
[r3]ospf 1
[r3-ospf-1]area 1
[r3-ospf-1-area-0.0.0.1]abr-summary 172.16.32.0 255.255.224.0
[r3]ip route-static 172.16.32.0 19 NULL 0

[r6-ospf-1-area-0.0.0.2]abr-summary 172.16.64.0 255.255.224.0

R7
[r7]ospf 1
[r7-ospf-1]area 3
[r7-ospf-1-area-0.0.0.3]abr-summary 172.16.96.0 255.255.224.0
[r7]ip route-static 172.16.96.0 19 NULL 0
R9
[r9]ospf 1
[r9-ospf-1]asbr-summary 172.16.128.0 255.255.224.0
[r9]ip route-static 172.16.128.0 19 NULL 0
R12
[r12]ospf 1
[r12-ospf-1]asbr-summary 172.16.160.0 255.255.224.0
[r12]ip route-static 172.16.160.0 19 NULL 0
特殊区域:
area0
[r1]ospf 1
[r1-ospf-1]area 1
[r1-ospf-1-area-0.0.0.1]stub
[r2]ospf 1
[r2-ospf-1]area 1
[r2-ospf-1-area-0.0.0.1]stub
[r3]ospf 1
[r3-ospf-1]area 1
[r3-ospf-1-area-0.0.0.1]stub no-summary
area3
[r7]ospf 1
[r7-ospf-1]area 3
[r7-ospf-1-area-0.0.0.3]nssa no-summary
[r8]ospf 1
[r8-ospf-1]area 3
[r8-ospf-1-area-0.0.0.3]nssa
[r9]ospf 1
[r9-ospf-1]area 3
[r9-ospf-1-area-0.0.0.3]nssa
area2
[r6]ospf 1
[r6-ospf-1]area 2
[r6-ospf-1-area-0.0.0.2]nssa no-summary
[r11]ospf 1
[r11-ospf-1]area 2
[r11-ospf-1-area-0.0.0.2]nssa
[r12]ospf 1
[r12-ospf-1]area 2
[r12-ospf-1-area-0.0.0.2]nssa
第五步:配置NET,使其均可访问R4环回。
R3
[r3]acl 2000
[r3-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r3-acl-basic-2000]q
[r3]int Serial 4/0/0
[r3-Serial4/0/0]nat outbound 2000
R7
[r7]acl 2000
[r7-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r7-acl-basic-2000]q
[r7]int g 0/0/0
[r7-GigabitEthernet0/0/0]nat outbound 2000
R6
[r6]acl 2000
[r6-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r6-acl-basic-2000]q
[r6]int s 4/0/0
[r6-Serial4/0/0]nat outbound 2000
第六步:加快收敛,需改HELLO时间,更改了hello时间死亡时间也会自动改变。
为了建立邻居关系,将hello时间区域内的其他路由器均改为一致的。
[r3]int t 0/0/0
[r3-Tunnel0/0/0]ospf timer hello 5
[r5]int t 0/0/0
[r5-Tunnel0/0/0]ospf timer hello 5
[r6]int t 0/0/0
[r6-Tunnel0/0/0]ospf timer hello 5
[r7]int t 0/0/0
[r7-Tunnel0/0/0]ospf timer hello 5
第七步:进行手工认证,区域认证(实际上也是接口认证),目的是为了更新安全。
[r1]ospf 1
[r1-ospf-1]area 1
[r1-ospf-1-area-0.0.0.1]authentication-mode md5 1 000000
[r2]ospf 1
[r2-ospf-1]area 1
[r2-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher 000000
[r3]ospf 1
[r3-ospf-1]area 1
[r3-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher 000000
