You can even enable that in the network we just built by just specifying `ecmp yes` in the OSPF configuration (try it on R2 or R6) and see what effect it has on the output of `ip r` on the linux command line. Just search for information on it on the Internet to learn more. * 'Cost' is an aspect that is fundamental to OSPF and the calculation of the shortest paths in the network. Traditionally, cost is related to the bandwith of a link between routers, and causes higher bandwith connections to be prefered above lower bandwith connections. Since we're working with switched Gigabit/s networks by default now, if it's not 10Gb/s, in the datacenter and even in our office, I've just been ignoring that. -Well, after completing this tutorial, I also encourage you to start reading the other "An Introduction to OSPF" like pages on the internet, since they should be a lot easier to understand while having seen it work for real! Have fun. +Enabling logging is also a nice way to get more insight in the way routing changes happen. There is no syslog daemon running in the containers which are used here, but BIRD can also directly log to a file. An example is to create `/var/log/bird` inside the container, chown it to the bird user, and then set `log "/var/log/bird/bird.log" all;` in `bird.conf`. + +Another thing you can play with is rolling out IPv6 on this little network that was just built. It needs a `bird6.conf` configuration file, and you'll soon find out doing IPv6 is very similar to what we did here with IPv4. Just pick some subnets from the `2001:db8::/32` network to work with and there you go. + +After completing this tutorial, I also encourage you to start reading the other "An Introduction to OSPF" like pages on the internet, since they should be a lot easier to understand while having seen it work for real!
