Currently, all my computers are in one vlan pointing to my router for their default gateway (i.e. 172.16.0.1 /16) Correct me if I am wrong, but after I set up Vlans and assign ports to them, I will need to make sure that the default-gateway of the nodes within each vlan points to the vlan interfaces IP addresses (i.e. 172.16.1.1 /24, 172.16.2.1 /24 and so on). If so, in order for the computers to be able to reach their old default-gateway should I configured the distribution switch to have that gateway as its gateway of last resort?
I am using a 4500 switch fo my distribution switch and variety of 3com and Cisco switches for access switch.
Once their mask says 24 bits only the people in 172.16.1.0/24 can reach the old gateway.
If you add the new gateway addresses as secondaries to the current vlan1 interface you can change everyones addresses/mask/ and gateway ahead of time. Then as you move each group from vlan1 remove the secondary address for that group and make it the gateway of their new vlan.
