6 DSVPN Configuration
About This Chapter
DSVPN can be configured on the source branch, destination branch, and central office routers.
6.1 DSVPN Overview
Dynamic Smart Virtual Private Network (DSVPN) is a technology that allows branches to use
the NBMA Next Hop Resolution Protocol (NHRP) to dynamically establish data forwarding
tunnels in the hub-spoke model.
6.2 DSVPN Features Supported by the AR1200
Before implementing the DSVPN feature on the AR1200, consider routing plans and configure
Multipoint GRE (MGRE) tunnel interfaces.
6.3 Configuring DSVPN
When Dynamic Smart VPN (DSVPN) is configured, IPSec does not need to be configured. If
IPSec is configured to protect GRE traffic, the remote IP address in an NHRP mapping entry
needs to be advertised to the local device to establish an IPSec tunnel.
6.4 Maintaining DSVPN
This section describes how to display the DSVPN configuration and clear DSVPN statistics.
6.5 Configuration Examples
This section describes how to configure DSVPN when different routing plans are used.
