Re: Bird vs Quagga revisited
Fell free to contact me if you have any questions about ExaBGP as I am painfully aware it's documentation is nowhere near what it should be.

You can use Quagga or Bird as a blackhole BGP injector, because the forwarding load is next to nothing and the number of prefixes in your blackhole RIB is likely to be small. You might - if you programatically get the blackhole criteria from your crm or some other database find ExaBGP to be easier to integrate with your data source. ExaBGP is a very lightweight BGP speaker that is perfectly suited for this purpose - http://code.google.com/p/exabgp/ Andy
Asia's Fastest Communications Cable Comes Online
http://www.livescience.com/22538-asias-fastest-communications-cable-comes-online.html The fastest-yet communications cable in Asia came online today (Aug. 20). The underwater fiber optic cable links Japan, Hong Kong, the Philippines, Malaysia and Singapore for high-speed, computerized stock trading. The system transmits information at 40 gigabits per second, three milliseconds faster than any other system in the region, the BBC reportedhttp://www.bbc.co.uk/news/technology-19275490. The gain may sound small, but could prove critical to financial trades made out of the region, according to the report. -- --- Joly MacFie 218 565 9365 Skype:punkcast WWWhatsup NYC - http://wwwhatsup.com http://pinstand.com - http://punkcast.com VP (Admin) - ISOC-NY - http://isoc-ny.org -- -

I am using BIRD as a RR between a busy VRF and our core and will not change it until the PPS are over what the box can pass :) EuroIX members were presented on a comparison of RR : ASR 1001 / 1002, Bird 1.3.6 / 1.3.7 / OpenBGPd - Quagga is not in the list as they do not use it , they migrated away from it after too many issues AFAICR. They found that both cisco routers which are designed to be used as RR and BIRD were performing very well (even more when you look at what CPU is on those cisco routers). The talk made at Euro-IX was under the password protected section but I found it on their site : http://www.ams-ix.net/downloads/AMS-IX%20Route%20Server%20Implementations%20Performance.pdf They presented their second testing at RIPE : https://ripe64.ripe.net/presentations/49-Follow_Up_AMS-IX_route-server_test_Euro-IX_20th_RIPE64.pdf Thomas

Both Quagga and BIRD have developed since the comparison in 2010: http://savannah.nongnu.org/news/?group=quagga http://bird.network.cz/?o_news But has anyone performed a more recent comparsion? Does Quagga still suffer from performance issues vs BIRD? Has anyone performed an RFC conformance test to see who complies more strictly to all the various RFCs? If BIRD is so much better than Quagga why is there no instance at Oregon: http://www.routeviews.org/ I also notice that BSD Router Project supports both: http://bsdrp.net/bsdrp How well do the two coexist at the same time? Any migration issues going from Quagga to BIRD? Any feedback appreciated.

We currently do blackholes via manual config on one of our real routers but are wanting to add a software-based (on linux) system where we could script a way for some of our tech support folks to add blackhole routes at the direction of a network person where they can just enter a command and the IP address. seems you want something like quagga on a secured host... that ought to be fine, you could even just make it an ebgp peer of 2-3 devices and use that with a route-map to reset the next-hop, there by not messing up your current nice ibgp mesh.

Re: Weekly Routing Table Report
Yup, the CIDR Report gets its feed in Australia... I get my BGP feed from APNIC's router in Japan - and at the time it grabbed the dump, the BGP table stopped at 190.55.80.0/21. Not sure what's going on, looks like the ssh session just hung, but then terminated normally - so the script's checking for hung sessions or early disconnects didn't catch it.
