setup scenario - need guidance

[ssphoenix]

Router configuration scenario.

Equipment:

„h 8 Buildings, 1 main building, fiber between all of them.
„h Catalyst 6500 multilayer switch in main.
„h Every other building, 3500XL catalyst switches with gigabit ports.
„h Main building has 5 3500XL switches clustered.
„h All servers are located in the main building and are attached to on switch.
„h I am running 4 subnets and 1 DHCP. The DHCP ip ranges are on every subnet from 50 through 250. Obviously the first 50 Ips of every subnet are restricted along with last 5.
„h Protocols: TCP/IP, IPX, UDP, HTTP, PPTP, and sure some other once.
„h Backend I have a 2600 Cisco router with two wan connections.

Questions:

I am interested in finding out several or the best setup scenario to maximize the traffic, security and redundancy.

All servers are located in the main building and are attached to on of the switches.

At the moment the current configuration has no trunking or vlans. More or less got it out of the box, setup an IP and was placed in the production. I am looking to implement and maximize the potential of the multilayer switch. Need to know what¡¦s the best configuration for trunking, vlans, spanning tree, need to route internally. Not interested in spanning ports through several switches. Our departments are pretty much balanced in terms of network resources use. Diagrams would be most appreciated along with some detail as to why.

Thanks in advance.

When you say router2 is connected to a remote lan via a leased line, is there a router at the remote site as well? IF there is a router there, the remote office would be a stub network with a default route from the default exiting interface.

How about the following configuration?

router1
ip route 172.16.2.0 255.255.255.0 172.16.1.253
ip route 0.0.0.0 0.0.0.0 bri0/0

router 2
ip route 172.16.2.0 255.255.255.0 int s0
ip route 0.0.0.0 0.0.0.0 172.16.1.254

pc client default-gateway = 172.16.1.254

Not sure if this answer your question.

Thanks for reply,

I am not concerned with the outside router as they will not changed. Reason, they are connectied to the corporate office. One of the question was wheater would be efficient and more secure to use the catalyst router as the gateway or should I leave the existing 2600 router as the gateway. All I want is to efficiently use the catalyst 6500 router.

Thanks
