Internal Routing Stack 3750X



How can i route internal VLANs on a 3750X , my current network its small ( about 8 -10 subnets) so i dont wnat to add overhead using maybe dynamic protocol , My scenario is my stack of 3750X ( 2 switches)  will be my CORE SW, i will have 2 stack more (2960S - 4 switches ) and it will connect to the 3750X with a trunk port etherchannel each link connected to a different switch, ( i was planning to use a L3 routing in the 3750X but not sure how it will works )

My core SW 3750X it will be connect with a firewall for aVPN , by a Layer 3 interface (using a static or dynamic protocol)

Usually routing protocols don't add too much overhead, especially in a network the size you're describing for yours.

If all the subnets have interfaces on the one "core" 3750X, all you need to do is enable routing and it will route between them.  If you have any other network(s) that is not directly connected, you can use a static route statement to tell your 3750X where the next hop is toward that network (also don't forget the reverse path).

Hello, I was planing in use EIGRP internally ( IP ROUTING , no ip clasless , EIGRP enable in 3750X ) and a static route from my SW3750X in order to reach the firewalls. ( 5515X), for the VLAN the 3750X will manage the VTP master, RPVST for the spanning tree (root 3750X stack) ,my only concern is if i will need to enable also the EIGRP in the firewall or it can work also with static routes for reach the internal networks ( like route X.X.X.X X.X.X.X Y.Y.Y.Y - for the internal network)

Each Access stack switch (2960S) will connected to the 3750X using a etherchannel of 2 ports.

Do you have an advice for the internal VLAN ( around 8 -10 )  and routing ?

Thank you ,
