EIGRP COPY COPY Flashcards
What are the 3 table in EIGRP
What IP Protocol does EIGRP use?
88 EIGRP
Reliable Transport Protocol
What does a EIGRP Hello Packet contain?
- Autonomous System # (two separate EIGRP Process will not share routes, you would need to redistribute routes).
- Hold down timer (does not have to match between router)
- Authentication
- Metric Weightings (K Values)
What address are EIGRP updates sent to?
224.0.0.10 ro unicast directly to neighbor
What best path Algrithum does EIGRP use?
DUAL creats a metric value.
What is Split Horizon?
Don’t advertise routes out the link they came in on
What is Quary?
To ask adjacent neighbors for a topology update.
DUAL Feasibility condition
- Finds loop free backup routes
- AD < FD, Path is loop-free and closer to destination. viable backup
Successor?
Best path to a destination (route)
It will be added to the routing table
Feasible Distance (FD)
Composite metric of best path (Metric)(Metric you advertise)
The total distance to the destination.
Feasible Successor (FS)
Backup Path to a destination
Advertised Distance (AD)
Composite metric learned from neighbor (Metric)(Metric you receive)
How far the destination is away for your neighbor.
Local Distance (LD)
Composite metric to reach local neighbor
ID the Successor and Feasible Successor paths.
The EIGRP Metric consist of 4 criteria. What are they
- Bandwidth (default)
- Delay (Default)
- Load
- Reliability
