Recovering Modifications and Deletions Performed for Existing Endpoints

Until Connectivity Services Director Release 1.0R2, the service recovery operation did not support the recovery of updated configurations made on existing endpoints associated with services. The only supported operations were recovery of new services and new endpoints for existing services, and recovery of connectivity fault management (CFM) profiles.

Starting with Release 2.0R1, the following recovery operations are supported in addition:

  • Recovering modifications to existing endpoints

  • Recovering endpoint deletions for a service

Also, recovery of the swap of hubs and spokes for hub-and-spoke IP and E-LAN services are supported. In addition, recovery of changes in configuration of backup endpoints for point-to-point A and Z endpoints is supported.

Recovery of templates, recovery for devices with different Junos OS versions running on them, and recovery of class of service (CoS) profiles are not supported.

Recovering Parameters for E-Line Services

Table 1 describes the fields or parameters that are supported for recovery during a service recovery operation and the corresponding XPath notifications for those configuration parameters. This table also denotes the service operation that is supported, such as creation, edit, or deletion of a service

Recovering Endpoint Deletions from a Service

The following scenarios are supported when recovering endpoint deletion from a service:

  • Recovery of a deleted endpoint for multipoint-to-multipoint E-LAN and full-mesh IP services

  • Recovery of a deleted spoke for point-to-multipoint E-LAN and hub-and-spoke IP services
