Re: Redunant GRE through Redundant Site-to-Site Tunnels using multiple ISPs and Routing instances

Hi Filaadmin,

Yes, I think you could just configure RIB groups and share interface-routes between the routing-instance using policy-options, then you won't need to add the physical interfaces under the routing instance hierarchy, defaulted on the inet.0.

here is a tech note about RIB groups

Hope it helps.
