BGP Redistribution Rules to Explicitly Advertise Host Routes and Routes that Do Not Exist in Local-rib

Resolution


Overview

There are instances where the Palo Alto Networks firewall has to redistribute host routes (routes with a /32 netmask, like loopback interfaces on the firewall) and routes that are not on the local rib (Rib-in) to the peers. The redistribution profiles do not have an option to select these host routes for redistribution, or the routes that are not on the routing table

Details

The redistribution of these host routes and the nonexistent routes into BGP can be achieved using the workaround below:

Configure a new redistribution rule under BGP by going to: Network > Virtual routers > BGP > Redistribution Rule

On the new Redistribution Rule window, configure the host route or the nonexistent networks in the “Name” field. Select the appropriate BGP attributes for these routes and check the “Enable” checkbox.
