Summary:
Cisco Systems has identified a service impacting bug in the current IOS version running on this router. A vendor recommended upgrade has been provided as a resolution and needs to be implemented immediately.
Original Issue Reference:
With the introduction of 4-byte ASNs (Autonomous System Numbers), a newly devised method of injecting a specifically crafted prefix into the global route table allows for the BGP process to be reset on older IOS code.

Customer Impact:
During this maintenance, customers will notice a complete loss of connectivity to their servers on the frontend network (public network). While the upgrade duration is scheduled for 1 hour, we only expect between 15-20 minutes of downtime as the routers reload and fully converge.
