This screen shows the VPN Concentrator routing table at the time the screen displays. The IP routing subsystem examines the destination IP address of packets coming through the VPN Concentrator and forwards or drops them in accordance with configured parameters. The routing table shows the valid forwarding paths that the IP routing subsystem knows about, from whatever source: static routes, learned via routing protocols, interface addresses, etc. However, the table lists only the best routesbased on metric and typewith duplicates removed.
To configure routing, see the Configuration | System | IP Routing and Configuration | Interfaces screens.
To update the screen and its data, click Refresh. The date and time indicate when the screen was last updated.
Click the Clear Routes button to clear the dynamic routing entries, such as RIP and OSPF, from the display. Clicking this button does not affect the display of static routing entries.
The total number of current valid routes that the VPN Concentrator knows about. This number includes all valid routes, and it may be greater than the number of rows in the routing table, which shows only the best routes with duplicates removed.
The packet destination IP address to which this route applies. This address is combined with the subnet mask to determine the destination route. 0.0.0.0 indicates the default gateway.
The subnet mask for the destination IP address in the Address field. 0.0.0.0 indicates the default gateway.
For remote routes, the IP address of the next system in the path to the destination. 0.0.0.0 indicates a local route. There is no next hop.
The VPN Concentrator network interface through which traffic moves on this route:
The protocol or source of this routing table entry:
The number of seconds since this route was last updated or otherwise validated. The age is relative to the screen display time, for example: 25 means the route was last validated 25 seconds before the screen was displayed. 0 indicates a static, local, or default route.
The metric, or cost, of this route. One is the lowest value; sixteen is the highest value.
