I have two Cisco 3750 switches. Each switch has a single VLAN. I want to configure routing between the two 3750 switches without using any other equipment. How do I configure this?

George,
You need to have IOS feature set as IP services or Advanced IP Services to enable OSPF. You can check it by using a "show version" command.
Regarding the configuration. It's not hard. You just create 3 networks as I mentioned. You then enable OSPF(if supported) on them.
For Sw3750 here you go :http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_50_se/configuration/guide/scg.html

George,
You're going to test routing between L3 switches. So you should assign 3 networks between them.
(Network1) ---SW3750_1---(Network2)----SW3750_2---(Network3)

Is there a document which shows this type of configuration?

Will the switch support OSPF routing? How would this be configured?

Can you stack the switches?
If not, besides what Toshi notes, static and RIP routing is included in the base IOS image (saves you up to $4K [per 3750] in licensing).

hi,
you can try this .. lets say your network looks like this..
net1--[SW1]--net2--[SW2]--net3
network 1 is 192.168.1.x/24
network 2 is 192.168.27.x/29
network 3 is 192.168.3.x/24
On SW1 do this.........................
interface GigabitEthernet1/0/22
description SW1-SW2 link
switchport access vlan 2
interface Vlan1
ip address 192.168.1.254 255.255.255.0
interface Vlan2
ip address 192.168.27.1 255.255.255.252
router rip
redistribute static
network 192.168.1.0
network 192.168.27.0
On SW2 do this ..........................
interface GigabitEthernet1/0/22
description SW1-SW2 link
switchport access vlan 2
interface Vlan1
ip address 192.168.3.254 255.255.255.0
interface Vlan2
ip address 192.168.27.2 255.255.255.252
router rip
redistribute static
network 192.168.3.0
network 192.168.27.0
=========end================
you can try static routes if you dont want to use RIP
hope this works for you .. plz rate if helpful

After I have created the VLans, how do I provide IP address for the specifice ports assigned to a VLAN?
06-16-2009 09:27 AM
The IP addresses for each port will be automatically assigned, when a computer is connected to the port. Each computer must be configured with an IP address in the subnet, for the VLAN of the port, to which it will be connected.
