I have 10 cisco 3524 switches that I've configured with various VLAN's (vlan 10, 20, 30 and so forth). Unfortunately, they're L2 switches and cannot route traffic amongst vlans. The idea was to connect it to the TZ210 router from Sonicwall but the TZ series does not have the feature to create sub interfaces vlan routing (only the NSA series do--which are too expensive).
So, the solution was to have a cisco 2650 router in the middle to support the multiple VLANs only, and have the tz 210 take care of all other routing, intrusion detection, vpn, etc features.
Here's the topology: Internet-----TZ 210 Router-----Cisco Router (2651)----cisco switches (3524's). Subnet is a /24.
Question 1: Since I only need to configure the cisco 2651 to support multiple VLAN's---what all do i need to configure to make it functional? Do i even need Nat, ip route--inside, outside as I would if it was to perform as a sole router?
I was thinking of making FE0/0 connect to the TZ 210 with the IP from the LAN (same subnet---ex. FE0/0 ip--10.1.10.253 and the tz210's IP: 10.1.10.254) and FE0/1 (10.1.10.1) connect to the switch (10.1.10.2), not enable NAT and just have sub interfaces on FE0/1 for each Vlan. Am I on the right track?
I think the easier question is, what steps (Outline) are needed to connect the above topology on the cisco 2651 and the TZ 210 to the switches while supporting the VLANs.
Your help is much appreciated!
