Layer3 Routing with 3 HP 2920 Series Switches and 1 WatchGuard Firewall Opinion on configuration

We set up a complete new network infrastructure,

which works as we want to but since we are not that

experienced with Routing and several switches we

would like to know if we can improve the configuration

of that switch setup.

 

Basically we got two VLANs, VLAN21 (Servers) and VLAN24 (Clients) and both VLAN

have to communcate with each other. DHCP-Server in VLAN21 has to deliver IP-Adresses

also to clients on the VLAN24. We want the Switches to do all the "internal" routing, not the

firewall. Firewall should only come into play when there's a route the switch doesn't know.

 

 

here is the scenario, 3 Switches, each one in different location:

 

1x 2920-48G "Switch1"

This is the main room with servers and where most of the clients are connected.

This is the most important switch

 

 

1x 2920-24G "Switch2"

Here are some redundant server system and other network devices including the Firewall

and the Internet Access. 

 

 

1x 2920-24G "Switch3"

Mainly only Clients are connected to this Switch.

 

 

Because of the given cabeling in the Building Switches are connected like this with each other.

Switch1 is connected with Switch2 via 1GBit Fiber.

Switch2 is connected with Switch3 via 1GBit Fiber.

 

Firewall is 172.21.0.254 and 172.21.0.254, a static route to it is entered in each switch.

Routing is activated on each switch.

 

I added also a show run of the switch configs.

 

I would apreciate you opinions to this configuration and how we can improve this eventually.

 

kind regards
