> At this time we believe we have found a Cisco day 0 network  
> vulnerability.
> We have 20+ routers in our core network - 6 of the 20 have the  
> identical route
> processor and IOS version.  These 6 have been affected in 3 separate
> geographical locations in the past several days.  The network issues  
> range
> from simple SNMP failure to loss of BGP or OSPF communications.   
> These are
> creating black holes intermittently across our network. We are  
> experiencing as
> much as 20% of networks not available at this time.
> We have been coordinating with Cisco for the past two days and have  
> deployed
> patches to address the problem.  Overall, we have determined that  
> the fastest,
> surest path to restoring 100% network normality is to replace these  
> 6 routers.
> We will continue this process to replace these 6 routers.
> Two of the six affected routers have already been replaced and  
> clients have
