Re: Looking glasses with programmatic interface?
### On Wed, 23 Jan 2002 14:39:45 -0500, "Deepak Jain" <[email protected]> ### casually decided to expound upon "Vincent Gillet" <[email protected]>, ### "Stephane Bortzmeyer" <[email protected]> the following thoughts ### about "RE: Looking glasses with programmatic interface?": DJ> This raises a good point. Since most LGs are running on a dedicated web DJ> server somewhere inside of a network, one could very easily install zebra on DJ> this webserver with a read-only BGP image from several internal routers [say DJ> all the borders]. This has two benefits: a) Queries do not bog down DJ> production routers in fact the load is linear, and b) The LG tool only need DJ> look at localhost for all answers. This only costs 120mb of RAM per view and DJ> saves network overhead to boot. I did something similar to this by hacking rsd to not export any learned routes, peered it with several border and core routers and then dumped the routing table once every 15 minutes into a program which reformatted it into RPSL objects that was then imported into irrd as a database. I used the source field to specify the router it was seen from. One could then query irrd for routes using whois. And one could also use the different search commands to get routes by AS, router, etc...

Or one could create an automated network health monitoring system that tracks path changes...
