Routing FAQ

Find answers to common questions about routing.

When editing route configurations through the web admin console, why are its advanced route settings made through the CLI, such as the BGP neighbor password, lost?

The web admin console only supports basic route settings. When you edit a route configuration through the web admin console, the firewall deletes the existing configuration and the associated advanced settings configured on the CLI. It then adds the new configuration with only the basic settings. So, relevant advanced route configurations are lost and you must reconfigure them.

If you have advanced route configurations, we recommend you always edit through the CLI. See Route configuration.

Why don't route configurations edited through the CLI appear on the web admin console?

You must run the write command to save route configurations made through the CLI so they reflect on the web admin console and persist on a firewall or daemon restart. See Configure BGP.

The CLI show command doesn't show the ibgp maximum-paths value when it's set to 16.

The firewall only shows custom values when you run the show running-config command. For example, it doesn't show the maximum-paths ibgp value if it's set to the default value of 16.

How do I make sure BGP uses the preferred route to a destination out of the routes it learns from different sources, such as from OSPF and a BGP neighbor?

Use the weight attribute to allow BGP to use the preferred route. BGP prefers the path with the highest weight.

For example, if it learns routes from OSPF and a BGP peer, the default weights are set as follows:

  • Locally originated: Routes learned from the router's own network, such as through a redistribute ospf policy. Default weight: 32768.
  • Learned from other networks: Routes learned, for example, from a BGP neighbor. Default weight: 0.

So, when BGP receives routes from both OSPF and a BGP neighbor to the same destination, it uses the route learned through OSPF with its higher weight.

To use the route learned through the BGP neighbor, set the route's weight higher than the OSPF route's weight.
