Good reference - BIRD seems pretty full-featured as it includes everything from static routing up to BGP.
The key idea is that if you have some code which turns a Linux box into a router (or really any box/server on your network), you can do the same thing to a Mininet node/host as long as you set up the configuration correctly (e.g. specifying per-instance configuration files when you start up each daemon.) If you run something like OSPF, however, you're probably creating more of a "legacy IP" network rather than an "OpenFlow" or "SDN" network I tend to prefer the idea of actually using (or building) a controller which handles IP routing using OpenFlow. ;-) Sometimes, however, you have to run legacy protocols (e.g. BGP) to connect to the legacy internet, so in that case something like BIRD can be very useful. -Bob On Jun 20, 2013, at 3:45 PM, Murphy McCauley <murphy.mccau...@gmail.com> wrote: > You can also get OSPF (or RIP) by running BIRD in a Mininet node, for example. > > -- Murphy > > On Jun 20, 2013, at 3:39 PM, Bob Lantz wrote: > >> It is not accurate to say that Mininet is "based on layer 2." >> >> The switches that Mininet uses by default are OpenFlow switches.
