OSPF Route advertisement from HUB to on-Prem issue

We have two vMX's in AWS and both of them are advertising same subnets two the MX which is on Prem  and we have OSPF between MX on Prem and Firewall . Route decision from On Prem MX is taken based on the Concentrator priority .. As per documentation Firewall should see all the VPN routes in OSPF table but we do not see routes advertised by vMX's in OSPF rest all routes from spoke are available in firewall route table .. Any suggestions how can we fix it i'm missing something ?Screenshot 2025-07-10 at 6.22.16 PM.png

Kind of a big deal

Have you got the AWS routes configured as "Local Networks" on the VMX in AWS?

I assume you are not using full tunnel mode.

Yes , i was advertising local network and tunnel was not full mode ..
Worked with Meraki support and they found this behaviour due a bug and suggested to upgrade to 19.1.9
