In packet-switched networks,
routers decide which direction, which neighbour to forward packets to. To make
these decisions they need to know the network topology more or less. Routing
protocols play an important role in gathering knowledge of complex network
topologies since routers can share topological information with each other this
way.
IPv4 and IPv6 routing
protocols are very similar but there are differences between them. This
presentation discusses the IPv6 unicast routing protocols in use today, their
new features and the differences compared to their IPv4 counterparts.
