Overview

The MPLS Manager is split into the following three components:

• MPLS Topology Server: This discovers the MPLS and VPN topology. The topology server works with the IP Availability Manager to discover the logical and physical objects in the physical-transport domain, the MPLS domain, and the VPN domain.

• MPLS Monitoring Server: This monitors the topology for status updates.

• MPLS Analysis Server: This analyzes the status updates to diagnose MPLS and VPN impacts.

  A Failover solution for the MPLS manager comprises of the following components:

• Active and Standby MPLS Topology Server

• Active and Standby MPLS Monitoring Server

• Active and Standby MPLS Analysis Server

  In the Standby MPLS Topology Server , auto-discovery and auto-pending discovery is disabled. In the Standby MPLS Monitoring Server, device polling and monitoring is disabled.

  In all the Standby MPLS servers (Topology, Analysis and Monitoring) auto-synchronization is disabled for all the underlying Domain Managers. That means,

• The Standby MPLS Topology Server will not synchronize with Active IP Availability Manager or Standby IP Availability Manager.

• The Standby MPLS Monitoring Server will not synchronize with Active IP Availability Manager, Standby IP Availability Manager, Active MPLS Topology Server , or Standby MPLS Topology Server.

• Standby MPLS Monitoring Server will not synchronize with Active MPLS Topology Server , Standby MPLS Topology Server, Active MPLS Monitoring Server, or Standby MPLS Monitoring Server.

  After each backup interval, the backup will happen from the Active MPLS Topology Server to the Standby MPLS Topology Server, from Active MPLS Monitoring Server to Standby MPLS Monitoring Server , and from Active MPLS Analysis Server to Standby MPLS Analysis Server.
