Recently we have been migrating to a non-trivial BGP setup, and I have had to experiment with the conditional advertising BGP feature in Palo Alto. I was familiar with this concept from cisco, but alas I still found the documentation available on this feature to be a bit unclear and lacking. So, I've written a how to with a step - by - step scenario in order to help the next person who comes along with the same questions I had.
I would be very appreciative if the community where to check the blog post here and give me their feedback / questions / mistakes that i've made, in order to better the article and hopefully even submit it as a document here on the paloalo knowledge point:
Many Thanks and Regards,
I found that article before finding this post. You can now monitor for the default route, which removes a limitation you mentioned.
The question I have is, can I make advertising a subnet conditional on the default route? I am thinking that it is possible that I didn't receive default route from my ISP for whatever reason, and then I don't want to advertise my public IP space to them. I know, kind of a weird problem, but just because I have an adjacency doesn't mean that all is well.
