You cannot change the MTU size of a tunnel interface using software after Cisco IOS Release 11.3(9.2).

 Workarounds:

  Use images between Release 11.3(5.1)T and Release 11.3(9.3) or Release 12.0(0.16) and 
Release 12.0(4.2).  Configure ip mtu on the tunnel interface before you configure tunnel 
destination. If tunnel destination is already configured, then unconfigure the destination, 
configure ip mtu, and then reconfigure the destination. You need to wait five seconds 
after removing the tunnel destination before issuing the ip mtu command. Once the workaround 
is issued, there should be no problems in the event of a router reboot as the ip mtu command 
is parsed before the tunnel destination.
