CCNP Routing & Switching ROUTE 300-101 Chapters 3 & 4 Notes:
- IPv6 Address breakdown
- 32 hexadecimal numbers
- 8 quartets
- 4 hex digits separated by a colon
- 128-bit IPv6 address
With the depletion of IPv4 addresses IPv6 was created to solve that problem.

CCNP Routing & Switching ROUTE 300-101 Chapters 1 & 2 Notes:
- There is a natural need for routing protocols
- The use of layer 3 devices
- The most common routing protocols used in an enterprise/campus networks are versions or RIP, EIGPR, OSPF
- Most common routing protocol used for external/untrust (Internet) networks is BGP
- There are 3 Routing Protocol Categories
- Distance Vector (Sends full copy of the routing table at certain interval)
- Distance-Vectore routing protocols use one of the following approaches to prevent routing loops:
- Split Horizon – This is when an interface is prevented to advertise a route which it already learned on that interface.
- Poison Reverse – This is when an interface receives a route advertisement but then re-advertises the same route out with a metric considered infinite.
Started my reading for the CCDA exam, a few important terms from the first chapter:
PPDIOO (Prepare, Plan, Design, Implement, Operate, and Optimize) – PPDIOO is basically an simple process which CISCO uses in deploying or managing services/technologies for a new or existing network.
