简单的VLAN无法通讯

myjieli

想要测试一下简单的VLAN间通讯，但是不行，是什么问题？
PC1和PC2分别划分在VLAN10 20，交换机之间使用truk并允许了所有vlan通过，但是pc1ping不通pc2.


在SW1上的配置:
[s1]display current-configuration
#
sysname s1
#
vlan batch 10 20
#
cluster enable
ntdp enable
ndp enable
#
drop illegal-mac alarm
#
diffserv domain default
#
drop-profile default
#
aaa
authentication-scheme default
authorization-scheme default
accounting-scheme default
domain default
domain default_admin
local-user admin password simple admin
local-user admin service-type http
#
interface Vlanif1
#
interface MEth0/0/1
#
interface Ethernet0/0/1
port link-type access
port default vlan 10
#

#

#
interface Ethernet0/0/22
#
interface GigabitEthernet0/0/1

port trunk allow-pass vlan 2 to 4094
#
interface GigabitEthernet0/0/2
#

#

#
return

在SW2的配置:

vlan也要配ip

gertcert2018

你需要在SW1上创建vlanif 10并为其分配一个ip地址
你需要在SW2上创建vlanif 20并为其分配一个ip地址

gertcert2018

对不起，应该是正确的方法,
你需要在SW1上创建vlanif 10 and vlanif 20并为其分配一个ip地址

不要同一个广播域内，肯定拼不通，可以做hybred 去除TAG标签

交换机配 ip

Derek@1

你的配置是纯二层的配置，然而VLAN的原理最基本的就是二层隔离，你现在配的两个不同的VLAN，自然PING 不通

没有IP 怎么能打开对方的大门

不通vlan间通信，需要三层路由
