Cisco router traditional bogons

This page aggregates all of the examples referenced on the Bogon Route Server Project (Bogons via BGP)page. Please see that page for full details of the Bogon Route Server Project, system requirements, caveats, etc.

With the advent of multiple bogon route-servers, the use of BGP peer-groups on Cisco routers is very convenient. Thanks to John Brown for the original example.

OpenBSD’s bgpd project can also be used to peer with the bogon route-servers. Our thanks to Pete Vickers for this example.

This example of how to configure a Mikrotik RouterOS box to use the Bogon Route Server Project is thanks to Ariel S. Weher.

Note: You can receive both IPv4 and IPv6 fullbogons over IPv4 transport. If you only requested one set of fullbogons, simply remove all references to the other set from the example above.

Thanks to Thomas Brandstetter for this example of configuring a Cisco router to receive the IPv4 and IPv6 fullbogons over IPv6 transit.

Thanks to David Hill at Hostcentral for the below example!

The following example will import and null-route the IPv6 fullbogons, peered over IPv4 transit, using the Quagga software router package.

If you wish to receive both IPv4 and IPv6 fullbogons over the same peering session, you will typically need to replicate the statements in the above example’s “address-family ipv6” section to an “address-family ipv4” section, with an appropriate change to the prefix-list applied to the peer-group.

PLEASE NOTE: As of version 1.3.11 Bird does not allow you to run IPv4 and IPv6 simultaneously. Therefore you should use EITHER bgp_cymru_v4_1 and bgp_cymru_v4_2 OR bgp_cymru_v6_1 and bgp_cymru_v6_2 in your config. x For dual-stack systems can run two instances of Bird with one peering over IPv4 and the other over IPv6.

PLEASE NOTE: ASA Firewalls began supporting BGP as of version 9.2.

PLEASE NOTE: For traditional bogons you only need to update the remote-as directive.
