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.
