Showing the Routing Table for Your Account

  • Updated

This article discusses how to Routing Table screen to show the ​routes for all traffic in your account.

  • Analyze the configuration for all static routes in the account

  • Monitor real-time changes in dynamic routing advertised routes

  • Show forwarding path information for a specific IP address

By default, the Routing Table screen shows all the routes from the routing table, routes that actively send traffic and learned routes. For example, with a high availability socket deployment, the learned routes for the stand-by socket are also stored in the routing table. When the stand-by socket becomes active, the learned routes are used to send traffic.

To show the real-time routing table:

  1. From the navigation pane, click Monitoring > Routing Table.

    The Routing Table screen opens.

  2. To only display the routes that are sending traffic, click the Show All Routes slider toggle.png.

    The slider is gray when this option is disabled.

Searching the Routing Table

You can search for sites and users according to the IP address or the name. The table is dynamically filtered as you enter the search string.

To search for sites or SDP users:

  • Enter the Name or IP/Subnet in the Search field. The screen is updated to show the matching results.

Tunnel Metrics for the Cato Socket

There are multiple tunnels that a site can use to connect to the Cato Socket and send traffic to the LAN or the Internet. The priority for these tunnels are based on the link quality and other factors. The Tunnel Metric is the value that Cato assigns to make sure that traffic is sent over the best tunnel. The lower the value for Tunnel Metric indicates that this tunnel has a higher priority. For example, in a High Availability deployment the active tunnel can have a metric of 5 and the tunnel from the passive socket has a metric of 10.

Understanding BGP Metrics in the Cato Socket

BGP metrics are used to prioritize routes when there is more than one distinct route to the same destination. In the Details column of the Routing Table, click the plus.png icon to expand the Metric Information for each route to better understand the real-time routes for your account.

BGP Metrics for Routing Decisions

These are the metrics that are used for routing BGP traffic:

  • More specific routes are selected over less specific routes (/24 over /22 and so on)

  • The order of preference for the following IP ranges:

    1. Static ranges

    2. Floating ranges

    3. Dynamic ranges

  • Lower Metric/Weight is preferred

  • Shortest AS-PATH is preferred

  • Lower Tunnel Metric is preferred

  • Lower BGP MED (Multi-Exit-Discriminator) from the route ID is preferred

Note

Note: You can expand Additional BGP Information to learn more about the AS in this route.
