1. Where we are in the layers? Intro to Routing layer.
   --> Control and forwarding planes (Reading and writing tables)
   --> Example of tables in a straight-line topology
   --> Intra-domain routing vs. Inter-domain routing (path metric vs. reachability)

2. Intradomain routing algorithms
   --> Link-state
       * Collect all measurements through broadcast and then run Dijkstra's algorithm.
   --> Distance-vector
       * Use local update rule at each note.
   --> LS and DV are really a family of algorithms, not just one algorithm.

3. Comparing link-state with distance vector routing
   --> Link state better when network is smaller
