h3c ospf stub total stub nssa
拓朴如下
Ip设置如下本实验只使用R1 R2 R3 R4:
实现区域1为stub
R1
[RT1]ospf 1
[RT1-ospf-1]area 1
[RT1-ospf-1-area-0.0.0.1]stu
[RT1-ospf-1-area-0.0.0.1]stub
R2
[RT2]ospf 1
[RT2-ospf-1]ar
[RT2-ospf-1]area 1
[RT2-ospf-1-area-0.0.0.1]st
[RT2-ospf-1-area-0.0.0.1]stub
和思科的设备一样,在stub中的路由器能学到一条默认路由
实现区域1为total stub
R1
[RT1]ospf 1
[RT1-ospf-1]area 1
[RT1-ospf-1-area-0.0.0.1]stu
[RT1-ospf-1-area-0.0.0.1]stub
R2
[RT2]ospf 1
[RT2-ospf-1]ar
[RT2-ospf-1]area 1
[RT2-ospf-1-area-0.0.0.1]st
[RT2-ospf-1-area-0.0.0.1]stub no-summary
和思科的设备一样,在total stub中的路由器能学到一条默认路由
实现区域1为nssa
R1
[RT1]ospf 1
[RT1-ospf-1]area 1
[RT1-ospf-1-area-0.0.0.1]nssa
R2
[RT2]ospf 1
[RT2-ospf-1]
[RT2-ospf-1]ar
[RT2-ospf-1]area 1
[RT2-ospf-1-area-0.0.0.1]
[RT2-ospf-1-area-0.0.0.1]nssa default-route-advertise
和思科的设备一样,在nssa中的路由器默认不能学到一条默认路由,所以要加上default-route-advertise
或使用如下的命令:
ospf 1
area 0.0.0.0
abr-summary 10.10.0.0 255.255.248.0
network 192.168.2.0 0.0.0.255
area 0.0.0.1
abr-summary 172.16.0.0 255.255.248.0
authentication-mode md5
network 192.168.1.0 0.0.0.255
nssa no-summary
#
结果看R1的路由表:
<RT1>display ip routing-table
Routing Tables: Public
Destinations : 14 Routes : 14
Destination/Mask Proto Pre Cost NextHop Interface
0.0.0.0/0 OSPF 10 1563 192.168.1.2 S0/2/0
127.0.0.0/8 Direct 0 0 127.0.0.1 InLoop0

192.168.1.0/24 Direct 0 0 192.168.1.1 S0/2/0

192.168.1.2/32 Direct 0 0 192.168.1.2 S0/2/0

测试在R1上:
<RT1>ping -c 1 -a 172.16.0.1 192.168.100.1
PING 192.168.100.1: 56 data bytes, press CTRL_C to break
Reply from 192.168.100.1: bytes=56 Sequence=1 ttl=253 time=20 ms
