VLAN 6850 & 6400

[tony83400]

In French :
Salut,

J'ai mon site principal (6850) où le vlan "data" est le VLAN 100 (192.168.0.0 /24). J'ai un site distant (6400) dont le vlan data est le VLAN 120 (192.168.210.0/24).

Les deux vlan communiquent.

Les deux sites sont reliés par des antennes :

- 172.16.23.2 sur le site principal
-172.16.23.1 sur le site distant

J'ai besoin de mettre un équipement sur le site principal, qui possedera une adresse de la plage du site distant.

Pour cela, j'ai créé sur mon switch du principal le vlan 120 en faisant :

vlan 120
vlan 120 name "Mon VLAN"
ip interface "Mon VLAN" address 192.168.210.254 mask 255.255.255.0 vlan 120
vlan 120 port default 1/43

Lorsque je connecte un équipement dans le vlan 120 sur mon site principal, les équipements de mon site distants deviennent injoignables.

D'où peut venir le soucis ?

Voici les tables de routages des équipements :

Sorry for bad traduction :

hello,

I have my main site (6850) where the vlan "data" is the VLAN 100 (192.168.0.0 / 24). I have a remote site (6400) whose data is vlan 120 VLAN (192.168.210.0/24).

Both vlan communicate.

Both sites are connected in wireless :

- 172.16.23.2 on the main site
-172.16.23.1 The remote site

I need to put a device on the main site, which will have an address in the range of the remote site.

For this, I created on my main switch of the vlan 120 by:

vlan 120
vlan 120 name "My VLAN"
ip interface "My VLAN" address 192.168.210.254 mask 255.255.255.0 vlan 120
vlan 120 port default 1/43

When I connect a device in the vlan 120 on my main site, the equipment of my remote site become unreachable.

What might be the trouble?

Here are the routing tables of equipment:
