Run through the archives to get a feel for what issues folk 
are facing. And these are just the issues that folk have 
decided to share.

There are others that aren't shared, or folk that aren't 
sharing entirely.

It's really dependent on how kinky you're running your 
boxes. If you look at my route reflectors (M120's), 10.4R4.5 
is solid, no issues. If you look at my PE Aggregation 
routers (MX480's, M320's, T320's), you don't want to know. 
If you look at the MX480 we're trying to make a BRAS, all 
bets are off :-).

The problem is that since Junos 9.4, we've all been thinking 
and hoping that the R4 release of that train (and all the 
ones following it) would be the ideal one. The solid one. 
The one on which we can hang our boots on and kick back.

But alas, that was never to be the case, and given we're now 
literally peeking at Junos 13 (or 14, or 15, whatever they 
decide to do after 12), it's amazing that we're all still 
chasing that ever elusive dream of a stable Junos.

Which, by the way, is not to discount all the good work that 
Juniper have done, particularly since the debacle that was 
Junos 10.2, but given that operators need to choose between:

	o Stable code.
	
	o Code that features you actually want.

	o Code that will be under Juniper EEOL program.

	o Code that will run new hardware.

	o Code that will fix all issues past without
	  bringing issues present.


... you can see where all the frustration is coming from.

What's worse, Junos 8 was a dream, so we all know what it's 
like to have good code :-).
