Examples: Applying Routing Policies

Configure the router to export to IS-IS the routes that match the dmz and local-customers routing policies:

[edit]

protocols {

    isis {

        export [dmz local-customers];

    }

} 

For three BGP peer groups, apply various export and import filters:

[edit]

protocols {

    bgp {

        group 1 {

            type external;

            peer-as 47;

            export local-customers; 

            import [martian-filter long-prefix-filter as47-filter]; 

            neighbor 192.168.1.4;

            neighbor 192.168.1.5;

        } 

        group 2 {

            type external;

            peer-as 42;

            export local-customers;

            import [martian-filter long-prefix-filter as42-filter];

            neighbor 192.168.1.4;

            neighbor 192.168.1.5;

        } 

        group 3 {

            type internal;

            export local-customers;

            neighbor 10.1.1.1;

        } 

    }

} 

Apply the long-prefix-filter prefix only to routes learned from a particular peer within a group:

[edit]

protocols {

    bgp {

        group 4 {

            type external;

            peer-as 47;

            export local-customers;

            import [martian-filter as47-filter];

            neighbor 192.168.1.4;

            neighbor 192.168.1.5;

            neighbor 192.168.1.6 {

                import [martian-filter as47-filter long-prefix-filter]; 

            } 

        }

    } 

}
