Vlan

Hello friends, I hope you can help me.

I have an Internet service and data transport with my ISP.

For the transport of data the ISP gives me a Vlan, this is the one that I must use to connect my branches, all with mikrotik.

There are 5 branches that I want to connect through the VLAN, each branch with a different network segment.

Branch 1: LAN LAN IP 192.168.1.0/24
Branch 2: LAN LAN IP 192.168.2.0/24
Branch 3: LAN LAN IP 192.168.3.0/24
Branch 4: LAN LAN IP 192.168.4.0/24
Branch 5: LAN LAN IP 192.168.5.0/24

On the VLAN interface that I created in each mikrotik of each branch, I created another subnet, example:

Branch 1: Vlan 600 IP 192.168.100.1/24
Branch 2: Vlan 600 IP 192.168.100.2/24
Branch 3: Vlan 600 IP 192.168.100.3/24
Branch 4: Vlan 600 IP 192.168.100.4/24
Branch 5: Vlan 600 IP 192.168.100.5/24

What I want is that each branch can have connection with the others through the Vlan. Pinging there is a response between 3 of the branches, but the remaining 2 do not receive a response, even when one of them I ping towards a branch, the connection of another falls.

Why does that happen? Do I have to declare something additional on the routes other than the default routes that are created?

I attach an outline

Are the device across the fiber the ones that can not communicate by chance?

Can you export the relevant part of your config (switch vlan or bridge vlan) so it’ll be easier to see? what i understand is that you have vlan600 which is for managment with range 192.168.100.0/24 and another 5 vlans and you can ping 3 of the branches, can you ping from the mgmt vlan, from office vlans, which branches? all trunk ports tagged with correct vlans?

We need your export
