Configure a GRE over IPsec VPN with IKE
3. For Destination Type, select the destination type.
You can select any type, including Default Gateway. The TMS zl Module
supports multiple default routes, so this is a valid option even when you
are configuring a floating static route for a redundant tunnel.
Refer to Figure 7-179 for help configuring the next settings.

4. If you have selected Network or Host, type the Destination Address, which
depends on the destination type that you chose:
• Network—type the IP address and subnet mask of the destination
network (behind the remote tunnel gateway).
• Host—type the IP address of the host (behind the remote tunnel
gateway).
The correct address corresponds to 4 in the example figure.
5. For Gateway Address, type the tunnel IP address of the remote tunnel
gateway (indicated by 6 in the figure).
6. For Metric, type a value to represent the distance to the destination
address.
If this is a route over a backup GRE tunnel and the primary tunnel also
uses a static route, type a higher value than that used in the primary route.
7. For Distance, type the administrative distance.
