Hello All,

I quite appreciate the multiple response I have gotten .

1. When i implement the route server client.. the Established BGP session
goes into active mode. so it has nothing to do with Layer 2
2. My BGP logs shows invalid or corrupt ASN received when the route server
client is implemented.
3.  My research shows that there are issues with quagga Route server client
: Mostly issues with rs-client code ,  Due to structure locking issues

   ( page 8 )
4. Bird..ah Bird .. Please Andy, i will be grateful if i can have the perl
script. We are a non profit IXP and as such welcome any contribution like
your to the exchange point.


Regards
Anibe Onuche

Hi, Anibe --

Unfortunately, the status on my BGP shows active  :-(

Your config looks correct.  (That said, your peer client in production

configuration should use route-maps or at the bare minimum

prefix-lists/distribute-lists in order to prevent leaks of non-customer

prefixes to the route-server.)


You should use standard BGP troubleshooting to look into this (I.e. Check

that layer 1/2 connectivity exists (you can ping); Check that you can

telnet from the route-server client to the route-server on port 179 and

get a tcp connection; check logs and debug output).



Tried working with BIRD routing protocol but some features lacking

(i.e peer groups),also the learning curve is somewhat steep.

Please do look again at BIRD.  If you are a not for profit Internet

Exchange point then you are welcome to my perl scripts that build the BIRD

route-server configuration at LONAP and IXLeeds in the UK.  The same

Scrips are used on the excellent NAP Africa IX in South Africa too.


They perform IRRDB filtering (which is a useful thing for you to do in

order

To build trust in the route-server service), and also individual RIBs

(routing tables) for each ASN connected to the route-server (which is

useful in the event that you want to offer filtering between route-server

participants.)


In my experience, BIRD scales further than Quagga, especially when you

have a routing table per connected ASN.


Good luck with your project.


Andy
