Monitoring Route Information

To view the routing tables in the J-Web interface, select Monitor > Routing > Route Information.

After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.

When you use an HTTPS connection in the Microsoft Internet Explorer browser to save a report from this page in the J-Web interface, the error message "Internet Explorer was not able to open the Internet site" is displayed. This problem occurs because the Cache-Control: no cache HTTP header is added on the server side and Internet Explorer does not allow you to download the encrypted file with the Cache-Control: no cache HTTP header set in the response from the server.

As a workaround, refer to Microsoft Knowledge Base article 323308, which is available at this URL: Also, you can alternatively use HTTP in the Internet Explorer browser or use HTTPS in the Mozilla Firefox browser to save a file from this page.

Apply a filter or a combination of filters to display relevant routes. Table 48 describes the different filters, their functions, and the associated actions.

To view the routing table in the CLI, enter the following commands in the CLI interface:

Additional Information

Static Route Addresses

The list of static route addresses.



Protocol from which the route was learned: Static, Direct, Local, or the name of a particular protocol.



The preference is the individual preference value for the route.

The route preference is used as one of the route selection criteria.

Next-Hop type

The next-hope type for the route.

If a next hop type is listed as Discard, all traffic with that destination address is discarded rather than routed. This value generally means that the route is a static route for which the discard attribute has been set.

If a next hop is listed as Reject, all traffic with that destination address is rejected. This value generally means that the address is unreachable. For example, if the address is a configured interface address and the interface is unavailable, traffic bound for that address is rejected.

If a next hop is listed as Local, the destination is an address on the host (either the loopback address or Ethernet management port 0 address, for example).


How long the route has been known.



Flags for this route.

There are many possible flags.

AS Path

AS path through which the route was learned. The letters of the AS path indicate the path origin:

  • I — IGP.
  • E — EGP.
  • ? — Incomplete. Typically, the AS path was aggregated.

Route Information

Route Information is shown for the selected route table with the following details: x destinations, x routes (x active, x hold down, x hidden) where x indicates the number of routes for that specific category.
