[j-nsp] rib group

[Truman Boyes]

Let's say that you have the following stanza under your master routing instance:

routing-options {
    interface-routes {
        rib-group inet if-route;
    }
    static {
        rib-group static-rg;
        route 0.0.0.0/0 next-hop 30.30.30.13;
        route 3.3.3.3/32 next-hop 30.30.30.10;
        route 220.220.220.1/32 discard;
    }
    rib-groups {
        if-route {
            import-rib [ inet.0 manhattan-alternate.inet.0 ];
        }
        bgp-rg {
            import-rib [ inet.0 manhattan-alternate.inet.0 ];
        }
        static-rg {
            import-rib [ inet.0 manhattan-alternate.inet.0 ];
            import-policy STATIC-RG-NO-DEFAULT;
        }
        ospf-rg {
            import-rib [ inet.0 manhattan-alternate.inet.0 ];
        }
    }
}

	
Take a look at the static-rg rib-group that has an import policy. In this example, I have an import policy that looks like this:

lab at cs-m10i# show policy-options policy-statement STATIC-RG-NO-DEFAULT
term default-reject {
    from {
        route-filter 0.0.0.0/0 exact;
    }
    then reject;
}
term accept {
    then accept;
}

This will reject the protocol static 0/0 route from inet.0 when copying to manhattan-alternate.inet.0. 

Hope this helps to make sense of RIB groups in JUNOS. 

Kind regards,
Truman
