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

I have the s0 interfaces in seperate routing-interfaces because i have 2 ISPs and each ISP has a seperate routing interface.  I think it is this way because i have seperate NATs on each ISP.  do i need to have my so interfaces in my r1 and r2 routing-interfaces, or can i move them to inet.0 and leave my ISPs in their respective routing-instance?  another reason i had the gr interface is because that is in my trust zone whereas i had to move the s0.0 and s0.1 interfaces to the zones associated with other interfaces in my routing-interface.  

r1 {
    instance-type virtual-router;
    routing-options {
        static {
            route 0.0.0.0/0 next-hop 1.1.0.1;
            route 192.168.12.1/32 next-hop st0.0;
            rib-group static-int1-to-main;
        }
        interface-routes {
            rib-group inet int1-to-main;
        }
    }
    interface ge-0/0/0.0;
    interface st0.0;
}
r2 {
    instance-type virtual-router;
    routing-options {
        static {
            route 0.0.0.0/0 next-hop 1.1.1.1;
            route 192.168.12.4/32 next-hop st0.0;
            rib-group static-int2-to-main;
        }
        interface-routes {
            rib-group inet int2-to-main;
        }
    }
    interface ge-0/0/1.0;
    interface st0.1;
}
