[j-nsp] Moving routes between VRF and inet.0

[Masood Ahmad Shah]

Here is how I would do that:

1. Import the routes into inet.0 by rib-groups (that is what you have
already done, great)
2. Assuming PE<>CE interface is 1.1.1.0/30 and working on the PE
3. Also I would not use “accept all” when doing import/export, so I created
a policy for that too.

<routing-instance>
floating {
    routing-options {
        interface-routes {
            rib-group inet COPY_FLOAT_TO_GLOBAL;     ## required for inet.0
to reach out to the next-hop of BGP routes
        }
    }

    protocols {
        bgp {
            group CE{
                family inet {
                    unicast {
                        rib-group COPY_FLOAT_TO_GLOBAL;
                    }
                }
                neighbor 1.1.1.1 {
                    peer-as ABCD;
                }
            }
        }
    }
}

<policy-options>
policy-statement pol-accept {
    term MY_ROUTES {
        from {
            route-filter xx.yy.220.61/32 exact;       # required prefix
            route-filter 1.1.1.0/30 exact;    # pe-ce bgp next-hop
interface route
        }
        then accept;
    }
    term NO_LEAKS {
        then reject;
    }
}

<routing-options>
rib-groups {
    COPY_FLOAT_TO_GLOBAL {
        import-rib [ floating.inet.0 inet.0 ];     # Primary table
floating.inet.0
        import-policy pol-accept;
    }
}


Cheers,
Masood
