Service PW template policies

Overview

Service PW templates policies enable you to automatically create SDP bindings on NEs that support BGP AD VPLS. PW templates contain the configuration to use when the NFM-P creates SDP bindings automatically through BGP AD. PW templates use the NFM-P policy distribution model to distribute the template to the NEs.

To prevent unwanted service disruptions, NEs do not automatically reconfigure SDP bindings when a change is made to the PW template from which they were generated. You can manually trigger a template re-evaluation to cause the NEs to re-configure SDPs to match the configuration in the template.

PW templates can be re-evaluated at three levels:

• service

• service site

• local definition of PW template policy

When you re-evaluate a PW template from the local definition of the PW template policy, the NFM-P re-evaluates the selected template for all of the VPLSs on the selected site.

When you re-evaluate a PW template from the service site, the NFM-P re-evaluates the selected template on the selected service site.

When you re-evaluate a PW template from the service, the NFM-P re-evaluates the selected template on all sites in the VPLS.
