Root-cause analysis
performs availability-based root-cause analysis of
the discovered EIGRP topology objects. It also relates physical-transport problems to the
EIGRP objects, along the affected data path, that are no longer accessible or experience
from lack of response or performance as a result of the physical-transport problems.
When detects an EIGRP failure,
it checks for any physical-transport problem from
IP Availability Manager
that
might be causing the failure. If it finds such a problem, diagnoses the EIGRP failure as a symptom and exports
the underlying physical-transport problem and the EIGRP symptom to
the Global Manager
, as explained in Chapter 4,
“EIGRP Cross-Domain Impact Correlation Analysis.”If
it does not find such a problem, focuses its analysis on just the EIGRP domain and performs
the root-cause analysis described in this chapter.
