Basic NLRI BGP
Synopsis
Main reason for the test is to see how exactly does BGP session establishment and update exchange look on the packet level. Debugs are included to complete the picture.text/html2010-02-15T11:25:33+01:00bgp:examples

ExaBGP - A BGP Route Injector
WE MOVED TO GOOGLE CODE
Please go to ExaBGP for up-to-date information.
What is it ?
A BGP speaker which can inject routes with arbitrary next-hops into your network to source some ipv4/ipv6 routes (using both IPv4 and IPv6 TCP connections) and/or mitigate DDOS using flowspec.
