PW template encryption

PW template encryption overview

PW templates allow you to automatically create SDP bindings. If the PW template is configured to use GRE delivery, there is no SDP configuration required, therefore no option to configure NGE on the services that make use of the SDP.

With PW template encryption, you can configure encryption on the PW template, providing encryption for the L2 services that will use the SDP. With PW template encryption, the NFM-P adds the NGE inbound and outbound encryption key-groups to a PW template.

This type of encryption can be useful for 7705 SAR-Hm networks that use the auto-bind function of the PW template for GRE-MPLS transport over the cellular interface.
