Weighted dynamic routing on edge - possible?

darren_g — Mon, 25 Aug 2014 04:16:11 GMT

Folks.

Current company is looking to expand to another site (yay for me - I get to upgrade my 2020's to 3020's at the head office!), however I'm in a bit of a quandary on getting the new site working.

The new site is going to have two internet links for diversity/redundancy, but I'm *not* going to be running BGP or any serious internet protocol at the edge.

What I'd like to do is terminate the internet (ethernet services) on the Palo Alto and run some form of weighted dynamic routing protocol - tell them to use link A as a primary, but if it fails to cutover to link B for the default route.

Does Palo Alto support something like Cisco's policy based routing to manage this? I don't want to just rely on link up/link down states to determine which link to run out of - I'd like to have some kind of active monitoring on the main link which knows when/if the link goes down and changes the default route to the second link.

Anyone know if this is possible? Or will it need manual intervention to cut over to the second link?

Thanks.

Sweet! Thanks.

The logic behind it is backward from what I would expect (the backup link being the default route), but I can make that work.

I assume this works on PanOS 5.x and 6.x as well?

Thanks again!

Hi Darren,

It works in all PAN-OS. Let me know for further difficulties.

That's great information Hardik, thank you.

I'll be sure to come back if I can't make it work.
