Affected Device: core01.tor1

Service Impacting: Yes - BGP Customer sessions will be gracefully turned down for the duration of this maintenance. All other BGP network traffic will be re-routed around device until the maintenance has completed.

Hello Everyone,

Just to confirm, the maintenance in question has been closed, without any serious incident. Core01.tor1's IOS is upgraded, now we are now able to deploy IPv6 allocations, network-wide.
