My comments & suggestions
parts of the route table, you should also add the "type of route" is shown in the table ( dynamic OSPF, static, bgp, etc.....) All of this is included in the route table. Also it's incorrect to say imho
Each route in the routing table includes the following element
Not all route includes every element, the type of route will determine if that element is included.
a connected route probably will never have a metric or priority
the quality of the route or routing could be mis-leading to a greenie or newbie. The proper description of distance should the "reliability" of the routing information or that's how cisco words it. The quality would make one thing one is better than the other and that might not reality be the case
You gave examples on RIP and OSPF but also ISIS and BGP have metrics
Overall a very good training block & nicely done , & more discussions should take place on routing within regards to multicast.
