Prevent OSPF routing loops - Area 0

[gcampbe9]

Hello,

We have a PA5050 with a couple of VRs.  

VR1 is the main VR with interfaces into the main customer networks, internet access and a 3rd party link

VR2 is for GlobalProtect clients and a separate internet link for the GlobalProtect Portals/Gateways

There is an eBGP Peer between the VRs so that VR2 can learn all the corporate networks and the GlobalProtect VPN client pools are redistributed from VR2 into VR1

We are experiencing an issue since moving a couple of Global Protect clients from VR1 to VR2 (10.100.140.0/23 and 10.100.142.0/23) with access over to the 3rd party now failing

There is an OSPF peer between VR1 and the 3rd party and we are advertising out the GP client pools 10.100.140.0/23 and 10.100.142.0/23 

However, we are seeing the OSPF peer advertise our client pools 10.100.140.0/23 and 10.100.142.0/23 back to us.  Any ideas as to why this might be happening and is there a method to filter out these updates from the specific OSPF Peer as I am reading this is not yet a feature on the PAN-OS. 

Thanks & Regards

Hello,

Is the 3rd party device setup to distribute the routes it learns? Perhaps its a misconfig in that device and not the PAN? I may have read the question wrong however.
