Hi CG,
Looks interesting. The route is exactly same on both the REs. Is it possible to try some steps to isolate this issue further?
1. Can we make the 2.2.2.0 route available in inet.0 table and see if backup RE is getting polled from SNMP server in 2.2.2.0 subnet?
2. Can we try to add a static route inside routing-instance instead of a BGP route to reach 2.2.2.0 subnet?
3. Can you also please share the "show route" outputs from MX960 having RE-2000s(from both backup and master RE) to see if at all there is any other difference?
Thanks
