User manual ALCATEL-LUCENT 5650 CPAM BROCHURE

[. . . ] The 7701 CPAA is fully managed by the 5620 SAM for centralized configuration, alarm collection and software upgrades. Key features Interior Gateway Protocol (IGP) management, assurance and troubleshooting IGP routing protocols are not sufficiently monitored to detect routing table changes that affect IP paths and LSPs and, as a result, services. For example, a switch to a redundant path or a path that is automatically rerouted around a major network failure is not visible to operators using element management systems to configure and monitor network infrastructure and services. This inability to capture dynamic control plane changes makes it very difficult for operators to troubleshoot problems because they do not know when the change occurred, what has changed or whether the change affected network operation. The 5650 CPAM makes it easy for operators to manage, assure and troubleshoot IGP by providing proactive and real-time visibility into internal routing issues. exceed certain thresholds for proactive notification of control plane activity that may affect services. [. . . ] Auto-OAM alerts operators immediately if a dynamic routing change has caused an undesirable condition, such as jitter or delay on a path. The 5650 CPAM provides near real-time detection of routing events and their impact. It leverages a tight integration with the 5620 SAM to automatically generate Proactive IGP control plane assurance Assuring the IGP control plane requires that IGP be audited for misconfiguration, that IGP configuration be easily validated and that IGP advertisements be monitored for abnormal activity or suspicious behavior. The 5650 CPAM audits IS-IS and OSPF configurations to automate discovery of IGP protocol misconfiguration. For example, operators can audit the network and routing interface configuration to reveal inconsistencies between related peers or incomplete configurations if no peer is found. With the 5650 CPAM, operators receive alarms when IGP advertisements 2 Alcatel-Lucent 5650 CPAM | Release 4. 0 | Data Sheet Table 1.

With the BGP RIB Info Browser, operators can take a snapshot of the current BGP RIB information. This allows them to efficiently verify the current configuration, to discover service-affecting discrepancies and track route changes over time. Operators can also monitor BGP IPv4 prefixes and trigger proactive threshold crossing alerts on significant BGP route changes to detect route removal and instability, route flapping and high watermarks. Managing BGP routes and peering points The 5650 CPAM includes a BGP AS Path View topology that allows operators to see the number of paths originating from and passingthrough each external AS path displayed. This view can be used to determine whether new peering points should be established Alcatel-Lucent 5650 CPAM | Release 4. 0 | Data Sheet 3 Proactive BGP control plane surveillance The 5650 CPAM proactively assures the service provider's AS, extending monitoring to external BGP peers, private customer AS peers and internal AS topologies, such as multi-AS, meshed, route reflector or confederations. Also, it allows network operators to receive alarms for a variety of route issues. For example, alarms are generated if the number of external routes changed will threaten network stability, or if the number of removals/additions or next-hop changes cross a predefined threshold (route flapping, high watermarks). Table 2. Using the 5650 CPAM topology map, operators can visualize the complex relationships between the service, network and control plane layers by highlighting services on the multivendor IGP topology map. This lets them compare historical and current paths for a given service. The 5650 CPAM also receives Multipath (MP)-BGP updates to offer better service availability for VPRNs (IPv4 VPNs) by monitoring connectivity between VPRN sites. Table 4.

It simulates typical operations, such as adding an adjacency, or taking down a node for routine maintenance or upgrades to verify the impact to IP and LSP paths. If paths are rerouted according to plan and no failed paths are recorded, the operator can pursue the configuration change with peace of mind. If some paths fail, the underlying cause can be found before the change is made. [. . . ] The tree discovery method uses SNMP queries or OAM tests to verify the actual path and attached leaf routers.
