| What command is used to enter a static route on a router? |
|
Definition
| ip route prefix mask {address | interface} [distance] [permanent] [tag tag] |
|
|
Term
| What is the maximum number of equal-metric paths to a specific network that can exist on a router? |
|
Definition
| As of 12.3(T), a router can have up to 16 parallel routes to a network. |
|
|
Term
| Which routing protocol can perform load balancing between unequal-cost paths? |
|
Definition
|
|
Term
| When configuring an IP dynamic routing protocol, which protocol does not require an AS or process number? |
|
Definition
|
|
Term
| What configuring an IP dynamic routing protocol, which protocols do not need a specific network specified? |
|
Definition
| You need the network command under the router configuration mode of all routing protocols except IS-IS and BGP. |
|
|
Term
| Which dynamic routing protocols allow you to specify a network and wildcard mask with the network command? |
|
Definition
| EIGRP and OSFP permit specification with a subnet or interface address and a wildcard mask. RIP allows only major network numbers to be specified. |
|
|
Term
| How does the use of the network statement in BGP differ from its use in other dynamic routing protocols? |
|
Definition
| The network statement in BGP tells the router to originate an advertisement for that network. Without the network statement BGP passes along advertisements it receives from other routers, but does not originate any network advertisements itself. |

Term
| What type of network topologies support on-demand routing? |
|
Definition
| The only type of network topology that supports on-demand routing is in a hub-and-spoke network. |

|
|
Term
| What global configuration command can be used to change the timer for CDP updates? |

|
Term
| When using a classful protocol, what command enables a router to select a default route to unknown subnets? |
|
Definition
|
|
Term
| Which is the only routing protocol that supports backup routes? |
|
Definition
| EIGRP is the only routing protocol that supports backup routes. |
|
|
Term
| What command disables auto summarization when used with routing protocols? |
|
Definition
|
|
Term
| What's the multicast address and UDP port that RIP-enabled devices use to listen for update? |
|
Definition
| RIPv2 uses UDP port 520 to listen for RIP update packets, and they are sent to mulitcast address 224.0.0.9. |
|
|
Term
| How much network and subnet information can be stored inside 1 RIP update packet? |
|
Definition
| RIP can fit up to 25 networks and subnets in each update. |
|
|
Term
| What type of security features are supported with RIPv2? |
|
Definition
| RIPv2 supports security between RIP routers using message-digest ot clear-text authentication. |
|
|
Term
| What is the default behavior of RIP onces its enabled on a router? |
|
Definition
| By default, the Cisco IOS receives both RIPv1 and RIPv2 packets, but it only sends out version 1. |
|
|
Term
| What type of network must be specified when using the network command with RIP? |
|
Definition
| Regardless of the RIP version, the network command using the classful network number is required under the RIP routing process. |
|
|
Term
| What command allows you to control the version of RIP updates that go through an interface? |
|
Definition
ip rip {send | receive} version {1 | 2| 1 2}
