Router on the stick configuration problem

Hi all,

I have some problem configuring router on the stick. Basically, here is the configuration on my router 2612 router running on 12.2(31) IP Plus. This router is attached to a Cat 2950 and its attached port is configured as "switchport mode trunk"

interface ethernet0/0 no ip address half-duplex interface ethernet0/0.1 encapsulation dot1Q 1 native ip address 10.0.0.41 255.255.0.0 interface ethernet 0/0.2 encapsulation dot1Q 2 ip address 10.16.0.41 255.255.0.0

Members in vlan 2 can ping 10.16.0.41 but members in vlan 1 cannot ping

10.0.0.41. If I change the configuration to this.... interface ethernet0/0 ip address 10.0.0.41 255.255.0.0 half-duplex interface ethernet 0/0.2 encapsulation dot1Q 2 ip address 10.16.0.41 255.255.0.0

Members in vlan 1 have no problem pinging to 10.0.0.41 and members in vlan 2 have no problem pinging 10.16.0.41. Any idea on what is happening? Both configuration are supposed to be valid and workable and but apparently the upper configuration is not working all all. Thanks in advance.
