VLAN interrouting

Hello,

I'm on an XGS1930-28hp.

I've configured some VLAN on it.

i'd like to interconnect a VLAN with another one directly on the switch. How can i do ?

thanks

    Hi @Toulouzzzz,

    I can ping the PC in another VLAN in my LAB. Please reference the handbook chapter 2.2 for the configuration.

    https://download.zyxel.com/XGS1930-28HP/handbook/XGS1930-28HP_2020.1.pdf

    Once the configuration is set, please visit Management > Routing Table > IPv4 Routing Table to check if the routing rule has been set.

    Then use tracert to check if the PC sends the packets to the correct gateway.

    By the way, I was unable to ping once because my laptop was connected to the Wi-Fi network, which caused it to send the packet to the network's default gateway.

    Hi @Toulouzzzz ,

    Could you share with us which management mode you are using, Standalone or Nebula?

  • Hi Zyxel_Judy

    A standalone mode.

    I've given an IP adresse to all of the Vlan (10.0.2.254 for the Vlan2, 10.0.3.254 for the Vlan 3...) and a 255.255.255.0 Mask

    I set the first computer (Vlan2) on 10.0.2.1 and gateway 10.0.2.254 and the other one (Vlan3) on 10.0.3.1 and gateway 10.0.3.254. but the first cant ping the other one

    Hi @Toulouzzzz,

    Are you able to ping after disabling the firewall on both PCs?

    If the problem still exists, please let me know.

  • Hi

    Everything is created as u explain.

    The first time I used tracert, the first ping i've sent was sent to the Wifi as u.

    I ve shut down the Wifi on my laptop.

    When I ping my switch (pluggin it directly on the same Vlan) tracert is running well.

    I tried to ping gateway Vlan3 (10.3.0.254) from laptop connected toi Vlan2 (10.2.0.11) and it works.
