Cards in this set: Term 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 EIGRP Term When configuring an IP dynamic routing protocol, which protocol does not require an AS or process number? Definition RIP 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 is used to enable ODR on a hub router? Definition router odr Term What is the default timer for CDP updates? Definition CDP updates are sent every 60 seconds by default Term What global configuration command can be used to change the timer for CDP updates? Definition cdp timer Term When using a classful protocol, what command enables a router to select a default route to unknown subnets? Definition ip classless 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 no auto-summary 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}
