Two options - VLAN interfaces, or turning your Layer2 ports into Routed interfaces:
1. Switch(config)# ip routing Switch(config)# int vlan 100 Switch(config-if)# ip add 1.1.1.1 255.255.255.0 Switch(config-if)# exit Switch(config)# ip route 0.0.0.0 0.0.0.0 1.1.1.254 2. Switch(config)# ip routing Switch(config)# int fa0/1 Switch(config-if)# no switchport Switch(config-if)# ip add 1.1.1.1 255.255.255.0 Switch(config-if)# exit Switch(config)# ip route 0.0.0.0 0.0.0.0 1.1.1.254 HTH, Aaron Rohyans IT Coordinator, IDC-USA [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> 317.244.8307 (V) 317.244.4600 (F) ________________________________ From: Chyka, Robert [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 12, 2008 2:55 PM To: NT System Admin Issues Subject: Quick Cisco test network question.. We are setting up a test network between 2 buildings. We have 2 strands of fiber that go from the one building into our data center. It is going to be a closed network with no internet access , so it will be isolated from our production environment. I have a cisco 3550 that will be the "core and on the other end we have a cisco 2950. it will be a windows 2008 test environment too, but we have to get the infrastructure in place first. We are going to set routing up on the 3550 (4 different vlans) and will have some servers and some clients on this switch. There will be no gateway out to the internet, totally closed network. I know you have to turn on IP Routing and set a default route, but where do I set up the routable network interface? As a vlan? For instance: Switch(config)# int vlan 100 Description routable network Ip address 192.168.1.1 255.255.255.0 Then route ip 0.0.0.0 0.0.0.0.0 192.168.1.1 Is this right? The switch doesn't seem to like it. Thanks..i have the advanced ip services image on the 3550. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
