bgpd questions
Hi! We are wondering about a certain bgp setup. We want to announce some private networks to a select group of neighhbors. Is it possible to define multiple networks in bgp.conf ? Can I choose which networks get announced to which neighbors ? I ask this because the manual states I can announce self, none, default-route, all. I am hoping I can use communities and or filters to achieve what I want. Any pointers/example configs would be nice. Regards, Frans

If you want more control you can write the filter rules yourself. Set a config file up with some announce and run it through bgpd -nv, you should see what to do.

In such cases it is best to add networks with a community tag network 10.1.2/24 set community $as:123 and filter on these communities later on to allow or deny the prefix. -- :wq Claudio

Thanks for both replies. Will report my findings when we have things running. Curious: Is there an OpenBGPD FAQ in the making ? I am sure you are all bgp guru's and what not, but I am a simple chela and need instructions ;p Regards, Frans

As a starter you could read http://www.openbsd.org/papers/linuxtag06-network.pdf This gives a brief introduction. -- :wq Claudio

Is it possible to define multiple networks in bgp.conf ? errr... yes of course. Can I choose which networks get announced to which neighbors ? yes, you need to write filters in that case. I ask this because the manual states I can announce self, none, default-route, all. so you chose self and filter out the private ones where you don't wanna announce them -- Henning Brauer, [EMAIL PROTECTED], [EMAIL PROTECTED] BS Web Services, http://bsws.de Full-Service ISP - Secure Hosting, Mail and DNS Services Dedicated Servers, Rootservers, Application Hosting - Hamburg Amsterdam
