VLAN set up issue on GS1920

Hi All,
I have the following set up:
MES3500 fiber switch and few GS1920s connected to it over fiber and one GS1920 connected via Ethernet on port 0/26.
All the switches have default VLAN 1 which is working fine.
I wanted to add VLAN 100. Please see below the network diagram.
 

The issue I have is that from switch sw-fr-01 I can ping all the other switches with VLAN 100 (which includes sw-fr-04, sw-fr-05, sw-fr-08 and MES3500), but I can't ping between any other switches:
sw-fr-05 to sw-fr-08
sw-fr-04 to sw-fr-05
etc.

I have configured trunks and VLAN tagging for VLAN 100 on MES3500 as follows





Similar set up on GS1920 switches (0/26 is uplink):





Any idea what I am missing?

Thanks

    Hi @brysmar

    Welcome to Zyxel Community.

    According to your description, here are questions that we would like to ask:
    1. What firmware version you use on switches?
    2. May you help us to put completed port number between switches on your topology so that everyone may understand what issue you have now?
    Remider: To ping an IP address on different VLAN, you should use "ping <IP address> + <VLAN number>

    For CLI:
    "ping 192.168.100.3 vlan 100" 

    For Web GUI:

    I work in a GS1900 environment, so it's a little different for me.

    If you're interconnecting two network switches, and simply trying to
    carry multiple VLANS across them, then just set up each
    interconnecting port just like this -

    VLAN1, PVID1, Untagged
    VLAN100, Tagged
    VLAN200, Tagged
    VLAN300, Forbidden
    . . .etc . . .

    Anything not tagged is presumed to be VLAN1
    because of your PVID1, and your other VLANS
    are static, and ostensibly tagged on your other
    switch-ports. . .   so Trunking and TX Tagging
    are superflous.

    So, in most setups, you shouldn't have to use
    VLAN Trunking or Tx Tagging. on interconnect ports.

    Other than that, I would go into the IP Interface settings
    for each switch, and make sure that each one has the
    correct gateway, VLAN, and subnet mask settings.

    Just out of curiosity, is there any particular reason that
    you needed to assign static IP addresses on both VLAN1
    and VLAN100 of your switches?   Normally, you'd just define
    your default VLAN, and leave everything else transparent.
