Re: Cisco GET VPN in transport mode

Hello Hans,

GETVPN doesn't work with transport mode because it uses Tunnel Mode with
header preservation, i.e. copy the original IP header information. Transport
mode isn't an option.

This allows you to use the existing IP routing table to route traffic and to
encrypt using a group Security Association (SA). No need for overlay routing
with the use of a GRE tunnel as you would in something like DMVPN. It also
allows Multicast traffic to follow the optimal path between sources and
destinations. Again depending on the underlying infrastructure.

Hope this helps.

Thanks,
Thomas
