OK wanted to make sure it was not me.   My config looks solid.

If you run into strange issues with GNS3 note them and move on.  Don't try to 
make sense out of something that was never meant to be production grade.

I am so baffled by this one.

I have a router that is trunked to a switch vlans 33 and 66 are running over 
it.  I have another router connected to the same switch ( access port ) in vlan 
33.  I can not ping.....  I try to ping from router to router and I just cant.  
If I put vlan 33 in as the "native vlan" vlan 33 works it works but only vlan 
33.  If I switch them I 66 works but not 33.


Configs.

Router A
Int fa0/0
No ip add
Int fa0/0.33
Encap dot 33
Ip add 10.5.4.5 255.255.255.0
Int fa0/0.66
Encap dot 66
Ip add 10.10.4.5 255.255.255.0


Router B
Int fa0/0
ip add 10.10.4.6 255.255.255.0


SW 1
Int fa0/2
Sw mode trunk
Sw trunk encap dot

Int fa0/5
