[c-nsp] Cisco VLAN configuration - total newbie

Hey all,
I'm a total newbie to Cisco VLAN configuration, and mostly a newbie to
VLAN's in general. I'd like to reconfigure one of my networks so that I
have a bit more control over it; here is what the network currently looks
like:
Cisco 7206VXR
e2/0 IP: 10.0.0.254/24, connected to a cisco 2950 switch
Cisco 2950
vlan1: IP: 10.0.0.253/24
fa0/23: uplink to e2/2
fa0/24: monitor
fa0/1-22: customers directly connected
The customers directly connected to fa0/1-22 just use IP's out of the /24;
kind of an ugly config, since any of them can just take another person's
IP and such.
I'd like to set up what I believe is called 'VLAN Trunking', where each
individual port of the 2950 is assigned to a VLAN, and a virtual ethernet
interface is created on the 7206 with a gateway IP for them. Here is the
configuration that I tried:
7206 config:
--
interface Ethernet2/2
ip address 10.0.0.254 255.255.255.252
no ip directed-broadcast
ip route-cache flow
no ip mroute-cache
full-duplex
!
interface Ethernet2/2.101
encapsulation dot1Q 101
ip address 10.0.0.6 255.255.255.248
no ip directed-broadcast
--
2950 config:
--
interface FastEthernet0/1
switchport mode access
switchport access vlan 101
interface FastEthernet0/23
ip address 10.0.0.253 255.255.255.252
--
When I bring up the 2950, I am able to ping 10.0.0.254, but a box
connected to Fa0/1 with the IP of 10.0.0.1 is not able to ping 10.0.0.6.
I know I'm missing something basic (may be going around this the totally
wrong way); I'd appreciate it if someone could clue me in. Thanks!
