Hi everyones,

I'm coming to ask you some help on one thing i'm not sure to fully understand.
Here the architecture i'm working with. 3 layers network (Core, distribution & access)



The vlan are declared in the Core, everything is in one bridge. The clients plug on the acces switch have the dhcp, internet. Everything is working but i'm not sure about differents things.
In the Distribution Switch, everything is one bridge, with trunk to deliver the Vlans to the Access switch.
To manage the Distribution & access switches, i declared the MGMT vlan direclty into them & gave it an ip with the MGMT vlan dhcp.

Then, should i need to give an ip address to the different bridges ? or direclty to the physical interface (like spf1...) ?
What is the better way to route my traffic after ?

I'm not talking about RSTP yet, just to understand wich interfaces i need to give an address or not.

Thanks for your time :)

In general, a switch only needs an IP address on its management interface. There is no need that a switch or bridge had an IP address in every VLAN, as there is no IP traffic a user device connected using that switch to that VLAN should exchange with the switch itself. Routing is done by the routers, and these must have an IP address in every subnet they host. Each subnet usually resides in its dedicated VLAN, although it is just the best common practice, not a law of physics.

Thanks Sindy for your answer.
I wasn't sure about all of this. At the end everything is working properly, but i was confuse.
At the end i just set the mgmt Ip and didn't setup the ip on the bridge.

Thanks so much :)
