BGP Scalability Simulation

Mon Sep 1 19:51:56 UTC 2008

Topology and setup of these kinds of tests largely depend on whether you are testing iBGP or eBGP. In my experience, eBGP testing is fairly straight forward as you are almost always testing reconvergence of the BGP next-hop.  iBGP testing scenarios on the other hand can be quite a bit more complex as you may also be testing the reconvergence of the underlying IGP if the BGP next-hop remains unchanged. Can you describe your testing goals and environment in a bit more detail?

Hi

I am trying to simulate BGP for scalability testing. I have few queries.

1) What sort of topology I should try out ?

2) What parameters should I test?

I am trying to simulate it in ns-2  and i would appreciate reply from you
guys.

Regards
