After Configuring a VPN, How Do I Configure the VPN on the Peer
Router?
SDM generates VPN configurations on your router. SDM includes a function that
will generate a text file of the configuration that can be used as a template to create
a VPN configuration for the peer router to which your VPN tunnel connects. This
text file can only be used as a template that shows you which commands need to
be configured. It cannot be used without editing because it contains information
that is only correct for the local router you configured.
To generate a template configuration for the peer VPN router:
Step 1 From the left frame, select VPN.
Step 2 Select Site-to-Site VPN. in the VPN tree, and then click the Edit tab.
Step 3 Select the VPN connection that you want to use as a template, and click Generate
Mirror.
SDM displays the Generate Mirror screen.
Step 4 From the Peer Device field, select the IP address of the peer device for which you
want to generate a suggested configuration.
The suggested configuration for the peer device appears on the Generate Mirror
screen.
Step 5 Click Save to display the Windows Save File dialog box, and save the file.
