For the EIGRP Neighbor Adjacency to be established, what needs to match?
Networks, the AS number, and metrics
In EIGRP, what is the lowest metric to the destination?
The Feasible Distance
Which table is used by EIGRP to store all routes that are learned from EIGRP neighbors?
The topology table
In EIGRP, what is a neighbor with a loop-free BU route that satisfies the Feasibility Condition?
The Feasible Successor
In EIGRP, when is the Feasibility Condition met?
Wwhen a neighbors RD is less than the local routers FD to the same destination network
How do EIGRP routers establish and maintain neighbor relationships?
By exchanging hello packets with neighboring routers
The Administrative Distance for an EIGRP Summary route is?
In EIGRP, when DUAL is finished routes are stable and?
Which command is used to display the bandwidth of an interface on an EIGRP-enabled router?
What algorithm does EIGRP use?
The data portion of EIGRP message is called?
Which EIGRP route would have the preferred administrative distance?
A summary route
EIGRP ______ ________ carry route info, only as necessary
What is indicated when an EIGRP route is in the passive state?
The route is viable and can be used to forward traffic.
True / False: EIGRP packets are use reliable delivery?
The Finite State Machine is?
An abstract machine that defines states, events that cause states & what events result from states
True / False: EIGRP supports authenticated routing updates much like OSPF and RIP?
EIGRP does not have a Dead-Timer, instead they have?
In EIGRP, what describes how an algorithm will react to events?
The Finite State Machine
In EIGRP, ff DUAL is recalculating/searching routes are?
What is an EIGRP Split Horizon?
Routes learned on an interface are not advertised out that interface are not advertised out that interface
The EIGRP packet header contains what number?
The AS number
What is the purpose of using protocol-dependent modules in EIGRP?
To accommodate routing of different network layer protocols
EIGRP Hello Packets multicast to what IPv6 address?
EIGRP is what type of Routing Protocol (Link-State | Distance Vector)
True / False: Some IOS versions allow you to use netmasks rather than wildcard masks with the EIGRP network command?
Acknowledgement Packets use unreliable or reliable delivery?
The Administrative Distance for an EIGRP Internal route is?
What command enables EIGRP on a router?
In 1992 Cisco took redeveloped IGRP and changed it to what?
EIGRP uses what to route different protocols?
Protocol Dependent Modules
What argument can be added to the show ip eigrp topology to show routes that are not feasible?
The default Hello-Interval for multiaccess networks is?
Every 5 seconds
RTP involves both Reliable and Unreliable delivery, what is the major difference between the two?

Where are EIGRP successor routes stored?
In the routing table and the topology table
EIGRP Routing Table only contains what?
What interval is the EIGRP Hold-Timer set to?
