CSR1000v Running on ESX 5.1

Hi Guys,

Hopefully someone can shed some light on this.  I have a CSR1000v running on ESX5.1.  Everything works accordingly exept that I get the message bellow when I create a tunnel interface.

Tunnel0: Maximum interface MTU over-ridden to 10132

I have search for this error unsuccessfully.   I have played around with the MTU sizes on the physical and tunnel interfaces but no luck. Has eanybody seen this or have a solution for it.

Thanks
