In this example, IP Availability Manager:
-
Diagnoses a NetworkConnection Down problem.
-
Generates a NetworkConnection DownOrFlapping event as an impact of the NetworkConnection Down problem.
-
Exports the NetworkConnection Down problem and the NetworkConnection DownOrFlapping event to the Global Manager.
-
Exports a NetworkConnection DownOrFlapping event to MPLS Manager.
MPLS Manager:
-
Receives the NetworkConnection DownOrFlapping event from IP Availability Manager.
-
Detects an impaired VRF_A and an impaired VRF_B for which the NetworkConnection DownOrFlapping event is associated with at least one of the interfaces that are underlying the impaired VRFs.
In addition, from the following PartOf relationships, VPN_A and VPN_B become impaired:
-
VRF_A
-

As indicated in GUID-A9CDD722-68AE-4F0D-8AB0-645A18BC8A15.html#GUID-A9CDD722-68AE-4F0D-8AB0-645A18BC8A15___MPLS_USER_CROSS_COR_EVENT_42943, MPLS Manager perceives the NetworkConnection DownOrFlapping event as a problem.
MPLS Manager then:
-
-
Generates the following four events:
-
VRF_A Impacted
-
VRF_B Impacted
-
VPN_A Impacted
-
VPN_B Impacted
-
-
Generates a NetworkConnection DownOrFlapping problem.
-
Correlates the four events with the NetworkConnection DownOrFlapping problem and marks the events as impacts of the problem.
-
Exports the NetworkConnection DownOrFlapping problem and the four events to the Global Manager.
The Global Manager:
-
Receives the NetworkConnection Down problem and the NetworkConnection DownOrFlapping event from IP Availability Manager.
-
Receives the NetworkConnection DownOrFlapping problem and the four events from MPLS Manager.
-
Combines the NetworkConnection DownOrFlapping event from IP Availability Manager with the NetworkConnection DownOrFlapping problem from MPLS Manager to form one notification that has two sources.
-
Associates the NetworkConnection DownOrFlapping notification as an impact of the NetworkConnection Down notification.
-
Associates the four event notifications from MPLS Manager as impacts of the NetworkConnection Down notification.
