#Download winbox 2.2 13 fullI was also planning on just pumping my original test devices, a couple of Olives, full of OSPF routes to see what happened - but then I got it in my head to see what all kinds of various implementations and platforms would do with a LSDB stuffed full of routes. The Python script doesn't take any care to avoid martians or bogons - it just spits out a random network with a random CIDR mask. Who will then sloppily redistribute these into OSPF. I coded up a Python script to generate a bogus IPv4 prefix, and used this in conjunction with a shell script and exaBGP to advertise prefixes to a BGP router, The really cool thing about it, is you can use scripts to announce and withdraw routes dyanmically. In a very brief summary, exaBGP is a BGP route announcer. I was planning on pumping a dump of a semi-current Internet routing table of about 400,000 prefixes I converted into static routes into OSPF,īut then I found an easier and "more scalable" solution when I came across a really cool program called exaBGP. This got me wondering just how many routes I could pump into OSPF, and what would happen when the lid on the LSDB overflowed. I pumped about 30,000 BGP NLRIs into OSPF, and then formed a redistibution loop and got some really awesome route oscillation going on. I recently did a lab demo where I illustrated the dangers of sloppy redistribution policies between different routing protocols (BGP and OSPF).
