I wasn't referring to pfSense, as the majority of service 
providers don't use it to forward customer traffic.

Actually, no - it's not just software. The interaction of 
integration of control plane software and mini-code that 
runs on line cards can be unpredictable when trying to 
implement things like ISSU.

Moreover, if you're going to run ISSU during a maintenance 
window, you're better off doing a proper upgrade. In some 
cases, folk who have used it have had stuff "left over" with 
all the warm reboots, and they end up doing a proper hard 
reboot to clear it all anyway.

I probably won't get into a war of words :-), but if you've 
had a chance to run IP/MPLS networks today, the quality of 
code is not as great as it used to be back in the day.

Mark.
