CCNP Routing & Switching ROUTE 300-101 Chapters 3 & 4 Notes Part I

CCNP Routing & Switching ROUTE 300-101 Chapters 3 & 4 Notes:

IPv6 Review:

  • IPv6 Address breakdown
    • 32 hexadecimal numbers
    • 8 quartets
    • 4 hex digits separated by a colon
    • 128-bit IPv6 address
      • Example:
        • FE00:0000:0000:0001:0000:0000:0000:0056

Summary:

With the depletion of IPv4 addresses IPv6 was created to solve that problem.

Progress:

CCNP Routing & Switching ROUTE 300-101 Chapters 1 & 2 Notes:

  • There is a natural need for routing protocols
    • The use of layer 3 devices
    • Scalability
      • 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 ReverseThis is when an interface receives a route advertisement but then re-advertises the same route out with a metric considered infinite.
