Re: Problem testing tunnelling - got it - need to do modprobe ipip

[Ranga Nathan <kairanga@xxxxxxx>]

Going through LVS Howto, figured out I needed to do:
           modprobe ipip
on the realserver to enable the tunnelling. This gives me tunl0 
interface to bind the VIP.
Sorry for my ass-about frequent posting.
