Most networks are not configured with only static routes or with only one
type of dynamic routing protocol. Most networks are a complex combination of
static routes, one or more dynamic routing protocols, manual and automatic
route aggregations, redistributions, distribute-lists, access lists, and more.
Understanding how these protocols and techniques work together and what effect
they can have on each other is essential in understanding and troubleshooting
networks.
The course examines these issues separately and, at times, in combination.
