Group Encrypted Transport VPN (GETVPN)

Hello Ray

Rene explains the difficulties that IPsec presents when you have a multi site WAN deployment. Even with DMVPN, it is difficult and cumbersome to employ IPsec within such a WAN topology.

The advantages of GETVPN will allow you to create a multi site WAN topology with a single IPsec SA, thus simplifying the implementation of IPsec into a multi site WAN topology.

So examples for the use of GETVPN include all multi site WAN topologies that want to employ IPsec in a scalable manner. For example, a corporation with a DMVPN hub and spoke topology with multiple spokes that want to employ IPsec over each and every connection for security and confidentiality.

GETVPN applies to any such multisite WAN topology simplifying its IPsec deployment with a single SA.

I hope this has been helpful!
