Viptela SD-WAN Solution Guide
The following sections describe how you secure a Viptela
SD-WAN with Prisma Access to provide next-generation security:
If you encounter issues after you configure the remote network, troubleshoot the Viptela
remote network.
Supported IKE and IPSec Cryptographic Profiles
The following table documents the IKE/IPSec crypto settings
that are supported with Prisma Access and Viptela SD-WAN devices. Use
the recommended settings when you Onboard a Remote Network (Cloud Management)and define IKE and IPSec cryptographic
settings when connecting the Prisma Access and Viptela SD-WAN
device.
A check mark indicates that the profile or architecture type
is supported; a dash (—) indicates that it is not supported. Default
and Recommended settings are noted in the table.
