Term
| default delay for tunnel interface |
|
Definition
|
|
Term
| protocol that ensures reliable neighbor discovery/recovery in eigrp |
|
Definition
|
|
Term
| what is the feasible distance (FD)? |
|
Definition
| the lowest calculated metric to a destination. |
|
|
Term
| when is the feasibility condition (FC) met? |
|
Definition
| when a neighbor's advertised distance is lower than the router's FD for the same destination. The FC is not met if they are equal. |
|
|
Term
| when can a router be a feasible successor for a particular route? |
|
Definition
| when the route via that router meets the FC. |
|
|
Term
| what is recorded in the topology table for each destination? |
|
Definition
FD.
all FS.
advertised distance for each FS.
locally calculated distance via each FS.
Interface for each FS. |
|
|
Term
| why should bandwidth manipulation be avoided when engineering eigrp? |
|
Definition
| because it may affect other apps such as ospf and qos. |
|
|
Term
| how do FS' improve performance? |
|
Definition
reduce the number of diffusing computations.
contribute to lower reconvergence times. |
|
|
Term
| what happens to a route when the link to it's successor fails? |
|
Definition
it will check the topology table for a FS.
DUAL will run if a FS can't be found. |
|
|
Term
| when does a route enter the active state? |
|
Definition
| when DUAL is being run for that route. |
|
|
Term
| can a router change the properties of a route in the active state? |
|
Definition
| No, DUAL must be completed first. |
|
|
Term
| briefly describe the diffusing computation. |
|
Definition
router sends query to all neighbors.
Neighbor replies if it has a FS.
Neighbor will also perform computation if it has no FS. |
|
|
Term
| when is the diffusing computation complete? |
|
Definition
| when a reply to every query has been received. This is when a successor is chosen. |

|
Term
| command to amend active timer |
|
Definition
|
|
Term
| what happens when the active-time expires for a route? |
|
Definition
route is considered SIA.
Neighbor that did not reply is removed from neighbor table. |
|
|
Term
| eigrp messages that reduce the liklihood of SIA routes. |
|
Definition
|
|
Term
| quick methods of verifying unequal cost load-balancing. |
|
Definition
1. compare traffic share in routing table.
2. compare hash buckets in cef table. |

| (256 * 10 Xy 7 / Bwmin) + (256 * DELAYsum) |
|
|
Term
|
Definition
(10 Xy 7 * 65536 / Bwmin) + (Delay [micro] * 65536 / 10)
this will provide the configurable delay i.e. 10's microseconds |
