【原创】H3C三层交换机的路由模式

网络拓扑图

将三层交换机当路由器使用

交换机配置

<H3C>dis stp brief
 MST ID   Port                                Role  STP State   Protection
 0        GigabitEthernet1/0/1                DESI  LEARNING    NONE
 0        GigabitEthernet1/0/2                DESI  LEARNING    NONE

当前启用了两个接口

[H3C]int GigabitEthernet1/0/1
[H3C-GigabitEthernet1/0/1]port link-mode route
[H3C-GigabitEthernet1/0/1]ip add 1.1.1.1 24
[H3C-GigabitEthernet1/0/1]ping 1.1.1.2
Ping 1.1.1.2 (1.1.1.2): 56 data bytes, press CTRL_C to break
56 bytes from 1.1.1.2: icmp_seq=0 ttl=64 time=1.335 ms
56 bytes from 1.1.1.2: icmp_seq=1 ttl=64 time=0.815 ms
56 bytes from 1.1.1.2: icmp_seq=2 ttl=64 time=0.942 ms
56 bytes from 1.1.1.2: icmp_seq=3 ttl=64 time=0.717 ms
56 bytes from 1.1.1.2: icmp_seq=4 ttl=64 time=0.820 ms

将端口设置为路由模式，配置IP地址，测试直连的计算机，OK。

第二个端口同样配置

[H3C]int GigabitEthernet1/0/2
[H3C-GigabitEthernet1/0/2]port link-mode route
[H3C-GigabitEthernet1/0/2]ip address 2.2.2.1 24
[H3C-GigabitEthernet1/0/2]ping 2.2.2.2
Ping 2.2.2.2 (2.2.2.2): 56 data bytes, press CTRL_C to break
56 bytes from 2.2.2.2: icmp_seq=0 ttl=64 time=1.190 ms
56 bytes from 2.2.2.2: icmp_seq=1 ttl=64 time=1.010 ms
56 bytes from 2.2.2.2: icmp_seq=2 ttl=64 time=1.036 ms
56 bytes from 2.2.2.2: icmp_seq=3 ttl=64 time=1.091 ms
56 bytes from 2.2.2.2: icmp_seq=4 ttl=64 time=1.058 ms

PC之间测试

PC1 : 1.1.1.2 255.255.255.0 gateway 1.1.1.1

VPCS_2> ping 2.2.2.2
84 bytes from 2.2.2.2 icmp_seq=1 ttl=63 time=1.220 ms
84 bytes from 2.2.2.2 icmp_seq=2 ttl=63 time=1.115 ms
84 bytes from 2.2.2.2 icmp_seq=3 ttl=63 time=1.402 ms
84 bytes from 2.2.2.2 icmp_seq=4 ttl=63 time=1.284 ms
84 bytes from 2.2.2.2 icmp_seq=5 ttl=63 time=1.564 ms

三层交换机上无需配置路由协议，自动完成路由。测试正常。
