CCNP Routing Chapter 1
Routing Protocols Fundamentals
How the Router Routes traffic
The Role of Routing in Enterprise
Bulding Access
Building Distribution
Campus Backbone
Edge Distribution
Internet Gateways
WAN Aggregation
Routing Protocol Selection
Scalability
Vendor Interoperability
IT staff's familiarity with protocol
Speed of Convergence
Capability to perform summarization
Interior or Exterior Routing (IGP or EGP)
Routing Protocol Interior or Exterior
IGP (RIP, EIGRP, OSPF, IS-IS)
EGP (BGP)
Routing Protocol Categorization
Distance Vector RIP
hop limit 15, 16 is consider infinite
Split Horizon (wont advertise learn route from same interface)
Poison Reverse
Bellman-Ford Algorithm
Advanced Distance Vector EIGP
By Default uses Bandwidth and Delay in its metric calculation
also has the following parameters Reliability, Load and MTU
Algorithm used >> Diffusing Update Algorithm (DUAL)
Link-State OSPF
Sends Link-state adversitements (LSA)
Algorithm Dijstra's Shortest Path First
Similar to the GPS used in cars
Sends full routing information at beginning, then send updates only
Link-State IS-IS
Same as OSPF, but not widely deployed as its link-state counterpart.
Path Vector BGP
Interchange packets between autonomous systems (AS)
There is an enhacement from BGP called Multiprotocol BGP (MP-BGP) supports IPv4 and IPv6
Network Technology Fundamentals
You will need to learn all different types of traffic types send trhough the network. Examples, Anycast, Multicast, Broadcast, point-to-point, nonbroadcast multiaccess (NBMA)
Network Traffic
Unicast
Broadcast
Multicast
Anycast
Network Architecture Types
Point-to-Point Network
Broadcast Network
Non-Broadcast Multiaccess (NBMA) Example Frame-Relay
TCP/IP Fundamentals
IPv4 packet header Format
IPv6 Packet Header Format
IPv4 uses ARP(broadcast), and IPv6 uses NDP(multicast)
Symmetric and Asymmetric Routing
ICMP packet header Format
TCP Segment Header Format
UDP Segment Header Format
TCP Chracteristics
Three Way Handshake
TCP Sliding Window
Out-of-Order Delivery
Network Migration Strategies
Migrate from one Routing Protocol to another
Using Administrative Distance (AD)
Using Route redistribution
IPv6 Migration
Check equipment for IPv6 compatibility
Run IPv4 and IPv6 concurrently
Check the ISPs IPv6 support
Configuring NAT64
Use NPTv6
IPv6 over IPv4 Tunnel
Spanning Tree Protocol Migration
Migrating to Rapid-PVST+
Keep:
PortFast
BPDU Guard
BPDU Filter
Root Guard
Loop Guard
Remove:
UplinkFast
BackboneFast
Migrating to Easy Virtual Networking
Virtual Routing Formarding (VRF)
VRF helps meet various industry regulations
Example regulation we got Sarbanes-Oxley Act and HIPPAA Privacy Rule
