BGP testbed tools

[ip at ioshints.info (Ivan Pepelnjak)]

This is how you can do it with Quagga:

You could write a Perl (or whatever your favorite scripting language is) script to get Quagga/IOS configuration from live BGP data, but it would be non-trivial and the resulting configuration would be enormous. I know there was a similar discussion months ago on the NANOG mailing list; browse the archives.
