What are 3 benefits of EIGRP?
|
Rapid convergence, multiprotocol support
(IP, IPX, & AppleTalk), supports VLSM &
CIDR
|
|
| 2 |
How is EIGRP similar to a distance vector
protocol?
|
EIGRP neighbors initially exchange full
routing tables.
|
|
| 3 |
What does EIGRP use to establish, keep, & maintain neighbor relationships?
|
Hello messages
|
|
| 4 |
How are hello messages transmitted and to what address?
|
Multicast to 224.0.0.10
|
|
| 5 |
What 3 requirements must be met in order to establish a neighbor relationship?
|
routers must receive hello messages from the neighbor, the Autonomous System Number & metric...
|
|
| 6 |
Which metrics does EIGRP use and which ones are used by default?
|
Bandwidth (default), delay (default), load, & reliability. The last 2 are not considered...
|
|
| 7 |
Name 3 tables kept by EIGRP.
|
Route, topology, neighbor
|
|
| 8 |
What are the terms used to describe the best route and the alternate route.
|
Successor & Feasible Successor
|
|
| 9 |
When there is no Feasible Successor, what does EIGRP use locate a loop-free route to a destination?
|
Diffusing Update Algorithm (DUAL)
|
|
| 10 |
What is a major advantage of EIGRP over RIP in determining routes?
|
EIGRP considers link speed in its metric rather than just hops.
|
|
| 11 |
Which show command displays both the Successor & Feasible Successor?
|
#show ip eigrp topology
|
|
| 12 |
What does FD stand for in the show ip eigrp topology command and what does it mean?
|
Feasible Distance. It is the calculated metric for the best route. When the...
|
|
| 13 |
When does EIGRP perform equal-cost load balancing?
|
When there are 2 successor routes to a destination.
|
|
| 14 |
How do you force unequal -cost load balancing?
|
With the variance command.
router(config-router)#variance <multiplier>
|
|
| 15 |
What does the "A" at the beginning of a line in the show ip eigrp topology output mean?
|
"A"=Active. It means that the route is unusable because that route is currently being...
|
|
| 16 |
What does the "P" at the beginning of a line in the show ip eigrp topology output mean?
|
"P"=Passive. The route is usable
