Dynamic Routing offsite

L2 Linker

I have been using small(ish) static routing tables until now.  I have 2 PA-3020 in HA mode that control the internet and new offsite datacenter.  At a second location 15 miles away, I will have a backup link to that datacenter.  A third 3020 is in place to handle the connection.  My plan is to install OSPF on the juniper gear controlling the internal network.  How do I advertise the two links to this new datacenter to the OSFP area from the Palo Alto's though?  I'm not very familiar with BGP but even a general idea/best practice would be helpful for me to start reading up on.  Rough map attached.























Ultimate goal: have access to the datacenter regardless if one link goes down without manual changes from me.

Have you looked into PBF and path-monitoring to accomplish the same thing with less complexity? Not saying that the OSPF idea isn't a good one, but if you aren't familiar with it I wouldn't really want my firewalls to be the place I learn how to configure things properly. 

The problem with that is that it assumes that site is available.  Secondary sites would still be routing there even if it went down.


Why not use OSPF all the way around? You mentioned OSPF and BGP. To make things easier, why not make everything area Using metrics should help out with any asymentric routing.
