Routes

Additional routes

The Additional routes feature allows expert users to add additional static routes for the CyberGuard SG appliance. These routes are additional to those created automatically by the CyberGuard SG appliance configuration scripts.

Route management

Your CyberGuard SG appliance can be configured to automatically exchange routing information with other routers. Note that this feature is intended for network administrators adept at configuring route management services.

Check Enable route management, select the Protocol you wish to use to exchange routes and click Apply. Once enabled, the routing manager can be configured by editing zebra.conf and protocold.conf (e.g. bgpd.conf) through Advanced ->Configuration Files.

For more information on configuring route management, refer to: http://www.zebra.org/
