This week, we were covering BGP semantics and scaling, plus just covered Multicast routing.
For fun, this is a report on how a mobile operator misconfigured OSPF and broke their network - it is salient here because a centralised controller such as discussed in "Fibbing" could have checked the config and shown it was broken before applying....misconfiguration errors in BGP are also problematic and have even more potentially global bad consequences than just messing up your own AS.
(OSPF=Open Shortest Path First, a very common link state protocol implementation used within quite a few ISPs - it also has some nice add on features such as Equal Cost Multipath, for load balancing).
