Using 3750 as Router

Hello,

I am replacing an Cisco 4006 with a Routing module. The replacement switch will be an stack of one 3750G and two 3750V2.

The Routing module of the 4006 has 192.168.1.3 as IP address. And does some routing to two gateways. all traffic for network 10.0.0.0 goed to 192.168.1.1(Cisco 2600) and the rest goes to 192.168.1.4(Firewall).

Both devices are connected to the routing module of the Cisco 4006.

How would I need to configure the new 3750 stack so it will function as a router and will be able to be used as gateway. And how to connect the other devices to the 3750 stack

Thanks in advance.

I have configured the two IP routes. They show up in the running config but not in when I use the sh ip route command.

Is this because the device is not yet placed in the network?

If I decide to use another VLAN ie. VLAN 10 for the router part of the 3750, the Cisco 2600 and the Firewall. Do I need to configure something zo VLAN 1 and VLAN 10 will be able to communicate?

The routes won't show up until the next-hop is reachable so yes you need to connect it up.

No, as long as "ip routing" is enabled on the switch you should be fine.
