Doh...I was reading the string half-way and got side-tracked when I just saw
MTU related messages. By the way I did the same lab yesterday and I did not
have the same issue. I was using CCOnlinelabs.com. Did you copy the configs
before exiting the lab?
BTW, was the interface vlan 105 up/up on the switch that had the IP address
configured for that SVI? This can be a good L2 troubleshooting exercise.
