The examples that follow show how Network Protocol Manager for OSPF uses the relationships between the OSPF objects and the underlying physical-transport objects to perform OSPF impact analysis. In addition, the examples show how the Global Manager picks up where Network Protocol Manager for OSPF leaves off to perform global impact analysis.
Keep the following information in mind when reading these examples:
A router has multiple physical interfaces.
A physical interface may have multiple OSPF interfaces.
An OSPF interface has one and only one OSPF neighbor endpoint.
An OSPF neighbor endpoint may have multiple OSPF neighbor relationships.
