|---|---|---|---|---|---|
| The time at which a route is totally removed from the routing table. | flush interval
🗑
|
||||
| A value used to determine the reliability and desirability of a particular routing table update. | administrative distance
🗑
|
||||
| A group of routers under the control of a single administration. | Autonomous system (AS)
🗑
|
||||
| The process of multicasting packets onto a network. | flood
🗑
|
||||
| An Exterior Gateway Protocol used to route between multiple autonomous systems. | Border Gateway Protocol (BGP)
🗑
|
||||
| What are the default metrics for IGRP? | Bandwidth and Delay
🗑
|
||||
| A static route that directs all traffic not specified anywhere else in the routing table to a particular route. Same as quad zero route. | default route
🗑
|
||||
| The point at which all routers on a network share a similar view of the network. | convergence
🗑
|
||||
| A routing loop whereby packets bounce infinitely around an internetwork. | count-to-infinity
🗑
|
||||
| A technique used with distance-vector routing protocols to prevent packets from bouncing infinitely throughout an internetwork by setting a maximum hop count | defining a maximum
🗑
|
||||
| A routing protocol that functions by broadcasting the entire routing table periodically to all connected neighbors. | distance-vector
🗑
|
||||
| A gateway protocol used to route between multiple autonomous systems. | Exterior Gateway Protocol (EGP)
🗑
|
||||
| A protocol that builds the routing table automatically. | dynamic routing protocol
🗑
|
||||
| A technique used to stop routing loops in which updates from an inferior source are not allowed for a certain interval. | hold-down timer
🗑
|
||||
| Multiple networks connected by routers. | internetwork
🗑
|
||||
| A count of the number of routers a packet must pass through to reach a destination network. | hop count
🗑
|
||||
| Updates that occur due to network topology changes, not periodic routing table advertisements. | triggered updates
🗑
|
||||
| A complex algorithm used by link-state routing protocols to determine the best path in an internetwork. | shortest path first algorithm (SPF)
🗑
|
||||
| A technique used by routers to prevent routing loops. | split horizon
🗑
|
||||
| A route manually added by a network administrator to the routing table of a router. | static route
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
