... is totally pwning me right now. Using a cisco catalyst 3550 switch, I have created 3 vlan's: vlan 5 - 172.29.5.1 vlan 100 - 172.29.100.1 vlan 101 - 172.29.101.1 I am now trying to setup the routing tables to get devices on the different vlans to talk. I have been following the walkthrough from here. But I am stuck at about step 6. Should my fastEthernet port 0/1 have been set to an IP that acts as the gateway for all 3 vlan routes?
