有關Juniper L2與L3 vlan串接,VLAN IP ping fail問題

123

腦中有一個問題,一直想不出來,上網查,也不知該設什麼關鍵字去google;

我有一台juniper ex4200 L3的Switch上面切vlan 50 (vlin_id :50),vlan ip :192.168.50.249,port1設定為trunk mode,設定方式如下 :
set interfaces ge-0/0/1 unit 0 family ethernet-switching port-mode trunk
set interfaces ge-0/0/1 unit 0 family ethernet-switching vlan members vlan50
set interfaces vlan unit 50 family inet address 192.168.50.249/24
set vlans vlan50 vlan-id 50
set vlans vlan50 interface ge-0/0/1.0
set vlans vlan50 l3-interface vlan.50

一台juniper ex2200 L2的Switch上面有切vlan 50(vlin_id :50),,vlan ip :192.168.50.250,port1設定為trunk mode,設定方式如下 :

set interfaces ge-0/0/1 unit 0 family ethernet-switching port-mode trunk
set interfaces ge-0/0/1 unit 0 family ethernet-switching vlan members vlan50
set interfaces vlan unit 50 family inet address 192.168.50.250/24
set vlans vlan50 vlan-id 50
set vlans vlan50 interface ge-0/0/1.0
set vlans vlan50 l3-interface vlan.50

L2/L3 上,當我把L2 vlan 50 Port1 與L3 vlan 50 Port1 對接, port1 狀態Link UP,L2與L3 Vlan50狀態Link UP,

但是我從L2 ping L3 vlan ip :192.168.50.249 卻不通(從L3 ping L2 vlan ip :192.168.50.250也不通),arp table也看不到L2與L3彼此的vlan ip

這個問題讓我想好久!

可以拜託網上各位先進幫忙解答嗎 ? 感恩。謝謝!!!
