I've had upto 512 LXC nested containers running quagga for bgp & osp to simulate "the internet". My machine is an i7 laptop and this used less than 8-10 gigs of ram to run. fyi the github of "The Internet" setup was from the 2014 NSEC conference where they used it so the participants had a large internet routing simulation available to test security. The github for "The Internet" simulation is here: https://github.com/nsec/the-internet https://github.com/nsec/the-internet "The Internet" creates 1 single LXC parent/master container and then 500+ Nested LXC containers each running quagga & setup for the simulation used.
