called C routers. In this example, C-routers are not part of the lab setup and are not managed by 
Prime Network. 
The CE devices are located at the customer site and can be managed by the SP. All other devices (PEs, 
Ps, and RRs) are located at the SP site. These devices are maintained by the SP.
An end-to-end MPLS VPN solution is, like any other VPN solution, divided into the central P-network...

CE-5 goes down or is reloaded.
Related Faults
The port S.1/2 of CE-5 operationally goes down (between CE-5 and PE-East).
The port S.2/3 of PE-East operationally goes down (between PE-East and CE-5).
CE-5 is unreachable from the management subnet.
NoteOther related faults might occur due to the CE-5 down or reload. Syslogs and traps corresponding to...

  Correlation Scenarios
NoteThe root cause selection process activates special filtering for the event [Device 
Unreachable, CE-5] for which the event [Link Down on Unreachable] cannot be selected as 
the root cause; therefore, the event [Link Down on Unreachable, PE-East < > CE-5] is not 
selected as the root cause.
For the event [Link Down on Unreachable, PE-East < > CE-5]:
Collected Events: [Device Unreachable,...

Prime Network Failure Processing
NoteThis scenario is similar to the one described in Device Unreachable on Device Reload or Device Down 
Event, page C-3, except that in this scenario the L3 Link Down is not discovered because both connected 
devices (RR2 and P-North) are unreachable by Prime Network. Therefore, the VNE is unable to detect 
the Link Down problem.

Clearing Phase
When a reloaded device comes up again (along with the L3 link that is vital for the RR2 management), 
the RR2 starts responding to polling requests from the RR2 VNE. The device is declared as reachable, 
thus clearing the Device Unreachable alarm....
