3500 Beginner

[Romer]

Just got a new 3500yl Switch and need help in configuring IP routing between VLANS. I currently have 3 VLAN's(VLAN 1, 2 & 3) on the switch. I need to configure IP routing only on 2 VLAN's(VLAN 1 & 3) and the remaining VLAN to be completely isolated. VLAN 1 is configured for ports 1-20, VLAN 2 FOR 21-30, VLAN 3 FOR 31-48. VLAN 1 is in the 172.16.0.0 subnet and 172.16.0.254 as the gateway, VLAN 2 on the 172.16.2.0 and VLAN 3 ON 172.16.1.0 subnet. Both VLAN 1 and 3 uses DHCP but i configured the switch to have a static IP of 172.16.0.250 on VLAN 1 and 172.16.1.250 on VLAN 3.

If you don't require any traffic routed to VLAN 2 you can simply not assign an IP address to the VLAN.

Otherwise you can use access control lists to selectively filter traffic going to that VLAN.
