[c-nsp] CEF flags explanation ?

[Brandon Applegate]

So I've been fighting a strange issue all day.  I have a prefix that is 
having reachability issues, and after exhausting all the normal 'internet 
is broken' checks, traceroutes etc, I find that a traceroute inside my own 
AS doesn't even work (well).  The one thing I find different about this 
prefix are the 'flags' from show ip cef x.x.x.x detail.  Other 'healthy' 
prefixes don't have this.  Routing table looks fine BTW.

router#sh ip cef 192.168.0.0 detail | inc flags
192.168.0.0/24, epoch 11, flags need ps clean

'flags need ps clean' - that's the head scratcher.  I have a TAC case 
opened on it, but I thought I might get a quicker and better answer from 
the list.  Thanks in advance.
