连接交换机的路由器设置步骤 交换机接无线路由器怎么设置( 二 )


int vlan30

⑤配置OSPF
在现实中,可以将S1上联到路由器的接口(G0/0/5) 用命令undo portswitch启用为三层接口,然后直接配置IP地址,以便与路由器配通,但是在模拟器中,我们只能把G0/0/5口放到某个VLAN,然后配置VLAN接口IP,以此与路由器配通
int vlan 100
ip add 10.1.1.2 30
int g0/0/5
p l a
p d v 100
ospf router-id 11.1.1.1
a 0
network 192.168.10.1 0.0.0.0
network 192.168.20.1 0.0.0.0
network 192.168.30.1 0.0.0.0
network 192.168.40.1 0.0.0.0
network 10.1.1.2 0.0.0.0
2、S2的配置,不多解释了:
stp instance 1 root secondary
stp instance 2 root primary
port-group group-member g0/0/1 to g0/0/4
p l t
p t a v a
int vlan 10
ip add 192.168.10.2 24
int vlan 20
ip add 192.168.20.2 24
int vlan 30
ip add 192.168.30.2 24
int vlan 40
ip add 192.168.40.2 24
int vlan10
vrrp vrid 1 virtual-ip 192.168.10.254
vrrp vrid 1 authentication-mode md5 hc
int vlan30
vrrp vrid 3 virtual-ip 192.168.30.254
vrrp vrid 3 authentication-mode md5 hc
int vlan20
vrrp vrid 2 virtual-ip 192.168.20.254
vrrp vrid 2 priority 120
vrrp vrid 2 authentication-mode md5 hc
vrrp vrid 2 preempt-mode timer delay 30
vrrp vrid 2 track interface g0/0/5 reduced 30
int vlan40
vrrp vrid 4 virtual-ip 192.168.40.254
vrrp vrid 4 priority 120
vrrp vrid 4 authentication-mode md5 hc
vrrp vrid 4 preempt-mode timer delay 30
vrrp vrid 4 track interface g0/0/5 reduced 30
vlan 200
int vlan 200
ip add 20.1.1.2 30
int g0/0/5
p l a
p d v 200
ospf 1 router-id 12.1.1.1
area 0.0.0.0
network 192.168.10.2 0.0.0.0
network 192.168.20.2 0.0.0.0
network 192.168.30.2 0.0.0.0
network 192.168.40.2 0.0.0.0
network 20.1.1.2 0.0.0.0
【连接交换机的路由器设置步骤 交换机接无线路由器怎么设置】int vlan 20
vrrp vrid 2 track interface GigabitEthernet0/0/3 reduced 30
vrrp vrid 2 track interface GigabitEthernet0/0/4 reduced 30
vrrp vrid 2 track interface GigabitEthernet0/0/2 reduced 30
int vlan 40
vrrp vrid 4 track interface GigabitEthernet0/0/3 reduced 30
vrrp vrid 4 track interface GigabitEthernet0/0/4 reduced 30
vrrp vrid 4 track interface GigabitEthernet0/0/2 reduced 30
3、S3的配置,不多解释了:
port-group group-member e0/0/1 to e0/0/2
p l t
p t a v a
int e0/0/3
p l a
p d v 10
stp edged-port enable
int e0/0/4
p l a
p d v 30
stp edged-port enable
dis stp ins 1 bri
dis stp ins 2 bri
S4和S5的配置,基本上和S3一样,就不贴出来了;
六、验证通讯:1、在R3上ping -a 3.3.3.3 192.168.10.21,可通;
2、在PC1上ping 3.3.3.3可通;
3、 在PC1上tracert 3.3.3.3,记住路径,S1的G0/0/3口 shutdown,在PC1上tracert 3.3.3.3,观察路径,竟然无变化

抓包显示,先到S2再到S1,再从R1出去,路径为次优,这个问题,在track了下联口后,已解决,如下图,4个VLAN在S1上全部都是backup,S2全为master,此时流量全部经由S2,上至R2出去;
