PC1的配置
pc1#config t
pc1(config)#no ip routing
pc1(config)#int f0/0
pc1(config-if)#ip add 192.168.10.1 255.255.255.0

PC3的配置
pc3#config t

pc3(config-if)#e
pc3(config)#ip default-g 192.168.30.254


我不知道哪里发生了错误,最后测试连通性,发现PC1和PC2之间能互通,PC1/PC2和PC3无法互通
pc1#ping 192.168.20.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.20.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/32/56 ms


pc1#ping 192.168.30.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.30.1, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)


真心请教,做了一天这样的实验了,就是会存在这种问题,帮忙看看到底哪里出了问题

在sw1 建 vlan 30 ,在sw2 建上valn 10 valn 20

sw1 少个VLAN30 做这种直接在PT上做简单明了
