Hi,Didnt say it was... it just that it came off the blue... (its started in 2003).
Snapshot dont compile yet on Freebsd.But those do: libgds-1.1.8-rc2.tar.gz <http://cbgp.info.ucl.ac.be/downloads/libgds-1.1.8-rc2.tar.gz> (May 17th, 2005), cbgp-1.1.20-rc2.tar.gz <http://cbgp.info.ucl.ac.be/downloads/cbgp-1.1.20-rc2.tar.gz> (May 17th, 2005)
I did spend a hour with the soft: . it is all the quality of good software... . small binaries... . fast.... large memory usage for simulation... (~128M for "valid-topology (July 15th, 2004)")
Where I could use it:Well, I can see it being used in a Net Dept (of a ISP with heavy use of IP routing and BGP) to check pre-depolyement of a new site... Simulation of the impact of a maintenance... etc.
I fail to see a usage for smaller ISP that are using BGP only for peering and OSPF internaly.
I would like to feed the full routing table, and zerba/quagga/bgp logs, or route-views data to see a play by play of evenements... and being able to inject command to try to control a evenement to reduce the impact on the net...
(that would have been cool) Have fun... Randy Bush wrote:
