Question : Problem: Cisco 3750 Config

I am trying to understand Cisco's use of VLAN1, the default VLAN.

I am creating a lab environment where every port will be on a different vlan with its own subnet 10.187.x.x, being able to route between VLANs

I want to connect the 3750 into my corp network as well, which I would is plugged into the default vlan 1.  I am not able to ping the other vlans.

Is vlan1 not routeable? Does this mean I have to create lets say vlan99 for my corp uplink?

Thanks

Answer : Problem: Cisco 3750 Config

Do you have "IP routing" enabled on the 3750?

en
conf t
ip routing

Did you assign an IP address from each subnet to the appropriate VLAN?

en
conf t
int vlan1
ip address 192.168.0.1 255.255.255.0
no shut

int vlan2
ip address 192.168.1.1 255.255.255.0
no shut

int vlan3
ip address 192.168.2.1 255.255.255.0
no shut

If you type "show ip route" do you see all of your VLAN subnets?
