Spoke Configuration

If you have configured a DMVPN hub, you can have SDM generate a procedure
that will assist you or other administrators in configuring DMVPN spokes. The
procedure explains which options to select in the wizard, and what information to
enter in spoke configuration windows. You can save this information to a text file
that you or another administrator can use.

Test the connectivity after configuring

Click to test the VPN connection you have just configured.The results of the test
will be shown in another window.
To save this configuration to the router’s running configuration and leave this wizard:
Click Finish. SDM saves the configuration changes to the router’s running
configuration. The changes will take effect immediately, but will be lost if the
router is turned off.
If you checked Preview commands before delivering to router in the SDM
Preferences window, the Deliver window will appear . In this window, you can
view the CLI commands you that are delivering to the router.
Spoke Configuration
This window contains information that you can use to give a spoke router a
configuration that will be compatible with the DMVPN hub that you configured.
It lists the windows you need to complete, giving you data that you need to enter
in the window so that the spoke will be able to comm unicate with the hub.
It provides the following data that you need to input into the spoke configuration:
•The hub’s public IP address. This is the IP address of the hub interface that
supports the mGRE tunnel.
•The IP address of the hub’s mGRE tunnel.
•The subnet mask that all tunnel interfaces in the DMVPN must use.
•The advanced tunnel configuration information.
•The routing protocol to use, and any information associated with the protocol,
such as Autonomous System number (for EIGRP), and OSPF Process ID.
