set interfaces ge-0/0/x unit 0 family ethernet-switching native-vlan-id vlan50
這一句應該不需要, delete掉

這是我設備介面trunk設定,給你參考看看
[edit interface]
ge-0/0/2 {
unit 0 {
family ethernet-switching {
port-mode trunk;
vlan {
members [ v77 v110 v200 v300 ];
}
}
}
}

Vlan設定
[edit vlans]
v110 {
vlan-id 110;
l3-interface vlan.0;

L3 Vlan介面
[edit interfaces vlan]
# show
unit 0 {
family inet {
address 192.168.110.253/24;
}
}

如果對接的port只需要通過一個vlan的話，把port-mode trunk刪掉，讓他走預設的access port
也就是在interface的設定上只要有vlan member那行就好了，兩邊的switch都一樣

set interfaces ge-0/0/6 unit 0 family ethernet-switching vlan members vlan50

interface的設定只留這行就好，其他delete掉

另外，可以show spanning-tree interface看看有沒有port loop被block掉

謝謝您的回覆!!!

請問一下，您說的L2 Vlan設定，
若是沒有綁interface vlan IP，那 L3-interface vlan.0 無法設定；

另外請問一下，您可以從目前的L2 ping到L3 VLAN_IP(192.168.110.253/24)嗎?

=========================================================================
EX2200 L2 :

root> show interfaces vlan terse
Interface Admin Link Proto Local Remote
vlan up up
vlan.0 up down inet
vlan.50 up up inet 192.168.50.250/24
=========================================================================
EX4200 L3 :

root> show interfaces vlan terse
Interface Admin Link Proto Local Remote
vlan up up
vlan.0 up down inet
vlan.50 up up inet 192.168.50.249/24
vlan.100 up down inet 192.168.100.249/24
vlan.224 up down inet 192.168.104.2/24
=========================================================================

L2、L3 的Vlan50 都已經是Link Up，

但是L2 & L3 vlan_ip彼此互ping，都是fail，

不知道到底是哪個地方出了問題 ???

我是EX2200 L2 interface ge-0/0/6 連接EX4200 L3 interface ge-0/0/6，

並且在兩端設定Vlan50做串接!!!


以上是L2 & L3 spanning-tree interface結果，
請問port loop有被block掉嗎?

若要給vlan一組ip需要把有設定L3-interface vlan.0的vlan套用到任一埠才可以commit成功,
我上面設定l3-interface vlan.0和interface vlan裡的unit 0是相關的

L3 Vlan介面,這邊指的不是L3 switch,而是vlan給予ip就算是跑l3了.
[edit interfaces vlan]
# show
unit 0 { //這邊unit 0 = l3-interface vlan.0 那串指令的vlan.0,你測試的環境要改50
family inet {
address 192.168.x.x/24;
}
}

照你設定若要給vlan ip兩台不管L2,L3交換器都需要l3-interface vlan.50這個

另我互ping是正常的
設定完可以先ping看看自己交換器設定的ip
L2 ping 192.168.50.250
L3 ping 192.168.50.249
先確保看看介面是否正確

您好，我照著您說的方式設定，但是L2 & L3 ping 192.168.50.249 & 192.168.50.250

都會出現 ping: sendto: No route to host

請問您知道是哪邊出現問題嗎?

謝謝歐......^^

把 me0 ip 拿掉 or 改成另一段
互連的 interface port-mode要相同

晚上好，請問一下，把 me0 ip 拿掉 or 改成另一段，

me0管理網段的ip不能跟vlan ip 同一個網段嗎?

是否我都把me0管理網段的ip、L2 & L3 VLAN 50 網段IP

都設定為192.168.50.X/24的因素，

才導致目前L2 & L3 VLAN 50 狀態都是LINK UP，

但是L2 & L3 vlan_ip彼此互ping，才會fail (L2跟L3都會出現 ping: sendto: No route to host")，

請問是因為這個因素造成的嗎???

謝謝大大的指點，今天總算把問題搞清楚了，

我把me0 ip改到10.x.x.x網段，L2 就可以pingL3 vlan ip 了。

謝謝討論版上所有大大的指點，再次感謝!!! ^_^
