EIGRP - EIGRP Fundamentals
6 important questions on EIGRP - EIGRP Fundamentals
In EIGRP the terms Successor and Successor Route are used, what do they mean?
2. Successor is the first next-hop router for the Successor Route.
In EIGRP, what is the difference between the Feasible Distance and the Reported Distance.
This turns into the Reported Distance when it is advertised to it's neighbors.
In EIGRP, what is the Feasibility Condition?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
A Feasible Successor is a route that satisfies the Feasibility Condition, where is it used for?
EIGRP contains a topology table, which makes it different from a true Distance Vector routing protocol. What are 4 properties of each entry in the table?
2. EIGRP neighbors that advertised that prefix
3. Metrics from each neighbor (Reported Distance, Hop Count, etc.)
4. Values used for Metric calculation (Load, Total Delay, Min. Bandwidth)
EIGRP uses IP Protocol Number 88 and when possible uses multicast address 224.0.0.10. Which 5 different packets does it send using this?
2. Request (Used to get specific information from specific neighbors)
3. Update (Used to transmit routing and reachability info)
4. Query (Sent out to search for another path during reconvergence)
5. Reply (Sent in response to a Query packet)
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
