Advertising a non-existent route to BGP in PAN
Normally if you want to advertise a route to your BGP neighbor, the route you want to announce must be available in your routing table but in Palo Alto Networks there is a nice trick which is quite handy. Where can it be really handy? For example you have a subnet which you only use in your NAT pool which doesn’t really need any next hop. In this case this config plays a nice role.
For example you want to announce your route 144.122.122.0/24 add this under the menu as screenshot and make sure your “Export” rules don’t really block this subnet being advertised otherwise you won’t see it in your RIB-OUT.
With the help of this handy config, your peer router will receive your nat-pool subnet although you haven’t really added this in your routing table (PAN does this dummy route automatically as far as I can see)
Palo has by far the worst implementation of redistribution of a null0 route. That routing static is pathetic.
hahahahaah agreed! All Palo BGP routing is horrible!
In general CLI navigation for me:)
Thanks man, you are life savior! Thank you.
Hero. Was trying to figure out to advertise a GlobalProtect IP pool and this was the key. Nice one.
Thanks for the feedback!
