i use quagga as active for bgp4 but i am searching openbgpd. I installed openbgpd on freebsd. i am new at openbgpd.

I have an AS and also my customer's AS. I have 2 IPSs for internet. how can i restrict sending all our prefixes towards my isps by AS or me and my ip prefixes ? Namely i want to apply filter not in order to send prefixes the isp from other isp. Could you give me an example ?

is there any mailing lists or forum about openbgpd ?

thanks

In your bgpd.conf you use the announce self configuration syntax (assuming you want to announce 192.168.1.0/24 from AS 100 to your neighbors at 192.0.2.1 (AS 777) and 192.0.2.9 (AS 778))...

# FILE: bgpd.conf
AS 100
network    192.168.1.0/24  
router-id  192.0.2.2

neighbor 192.0.2.1 {
    remote-as           777
    descr               upstream
    local-address       192.0.2.2
    announce            self
}
neighbor 192.0.2.9 {
    remote-as           778
    descr               upstream
    local-address       192.0.2.10
    announce            self
}

Also look up Henning Brauer's openbgp config notes

AS112 also has some good information

BTW, openbgpd is also available for pfSense, as it's a BSD-based platform

  • You will need to announce all to the upstreams and use filter language

    If you're going to run a complex network like this, there's no substitute for you actually learning BGP and the configuration language for the tool you've chosen to run it.

  • "announce all" and my customer AS200 and its prefix 192.168.200.0/24 and my prefix 192.168.1.0/24 by that of, announce all deny from any allow from any inet prefix 192.168.200.0/24 prefixlen >= 24 allow from any inet prefix 192.168.10.0/24 prefixlen >= 24 does it be enough ?
