In addition to this intuitive visual
topology display, routing architects
can trigger various queries that will
compute multi-area, end-to-end
routes based on real-time routing
information. The results are high -
lighted on the topology maps.
For troubleshooting MPLS protocols,
the 5650 CPAM provides super -
imposed MPLS and IP protocol
peering. This helps operators
detect incomplete MPLS or IP
peering that affect the MPLS
protocol’s operation.
The 5650 CPAM also includes a
powerful control plane configura -
tion search engine that detects and
highlights traffic engineering config-
urations that deviate from standard
implementations (e.g. different traffic
engineering parameters, incomplete
peering, available bandwidth
configuration, etc.)

The virtual private routed network
(VPRN), virtual private line service
(VPLS), virtual private wire service
(VPWS) composite services, MPLS
tunnels and LSPs provisioned
(active and alternate paths) in the
5620 SAM can be highlighted over
the 5650 CPAM control plane map.
This feature allows operators to
understand the path used to
traverse the network, the number
of hops along the path, whether
the forward/return paths follow the
same route and view all provisioned
alternate paths for a given LSP
[Figure 7].
Should the 5620 SAM SLA
monitoring feature report service
quality degradation, a network
operator can extract the OAM
trace results for the corresponding
MPLS tunnel (path) from the
5620 SAM and verify if the path
was recently changed. Any changes
are graph ically highlighted over
the control plane topology map
to provide a visual comparison
between previous and current paths,
which might account for the sudden
change in service quality.
