Configuring Protocol-Independent Routing Properties

Configure a router ID and autonomous system (AS) number for Border Gateway Protocol (BGP):

[edit]

routing-options {

    router-id 10.1.7.1;

    autonomous-system 222;

}

Configure martian addresses, which are reserved host or network addresses about which all routing information should be ignored. By default, the JUNOS software blocks the following martian addresses: 0.0.0.0/8, 127.0.0.0/8, 128.0.0.0/16, 191.255.0.0/16, 192.0.0.0/24, 223.255.55.0/24, and 240.0.0.0/4. It is also a good idea to block private address space (addresses defined in RFC 1918). You can add these addresses and other martian addresses to the default martian addresses.

[edit]

routing-options {

    martians {

        1.0.0.0/8 exact;

        10.0.0.0/8 exact;

        19.255.0.0/16 exact;

        59.0.0.0/8 exact;

        129.156.0.0/16 exact;

        172.16.0.0/12 exact;

        192.0.2.0/24 exact;

        192.5.0.0/24 exact;

        192.9.200.0/24 exact;

        192.9.99.0/24 exact;

        192.168.0.0/16 exact;

        224.0.0.0/3 exact;

    }

}
