How can you reduce routing table entries?. This can reduce the routing table entries.. List the key information routers need to route data Describe the use of the fields in a routing table Describe classful and classless routing protocols. Compare distance-vector and link-state routing protocol operation. Given a pre-configured laboratory network, discover the topology, analyze the routing table, and test...

RIPv2 provides which of the following benefits over RIPv1?. Which of the following are considered distance-vector? (Choose all that apply.). It sends periodic subnet mask information.. It sends incremental subnet mask information.. Which of the following protocols support VLSM? (Choose all that apply.). Which of the following protocols use only hop count to determine the best path to a remote...

Take a look at the way a Cisco 2500 series router asks you to put the subnet mask in the configura- tion when using the Setup mode:. When dealing with these ques- tions, remember that your answers involve the number of bits used for creating subnets, not the number of bits in the subnet mask. The industry standard is that...

Without this knowledge, the remaining sections of the chapter will be difficult to follow.. A DR and BDR must be elected for multi-access broadcast networks.. Point-to-point This type of network connection consists of a unique NMBA configuration. The network can be configured using Frame Relay and ATM to allow point-to-point connectivity. Router ID The Router ID is an IP address...

Point-to-Multipoint. The same ip ospf network broadcast command is used to specify that the network type is point-to- multipoint non-broadcast. This tells the router that no DR/BDR needs to be elected and that the interfaces are treated as individual point-to-point links.. RouterC(config-if)#ip ospf network point-to-multipoint non-broadcast. show ip ospf. This command is used to display OSPF information for one or...

network area 0 network area 1. network area 1 network area 1. RouterA (config)#router ospf 70 where 70 is the Process ID.. Next, we need to identify each of the networks connected to the router that we want to participate in the OSPF process. RouterA(config-router)#network area 0 where is the network and wildcard mask of a network connected to RouterA...

IGRP and EIGRP. S o far in this book, we have taken an in-depth look at the rout- ing protocol OSPF and shown how a routing protocol is used to find routes through the network. This routing process occurs at Layer 3 of the OSI model.. In this chapter, in order to decide on the best routing protocol or protocols...

Only when there is a change in the network topology. The neighbor table uses which of the following timers? (Choose all that apply.). When there are no feasible successors and only one link to a destina- tion network, even if the link cost is set to 100,000, the link will always be in which of the following modes?. Which of...

The BGPv4 speaker must then reopen the TCP session using the parameters used in the lower version of BGP.. This field indicates the autonomous system number (ASN) membership of the BGP router sending this OPEN message. Every AS must be identified by its own unique ASN, which we discussed earlier in the chapter.. This field indicates the amount of time...

The IP address of the loopback should be used for the peer address. Since the loopback interface is being used as the source of the BGP session, the interface-type should be entered as the loopback. The interface- number is the number of the loopback interface that is being used for BGP peering. Table 8.2 summarizes all of the commands that...

A prefix list is similar to an access list but is more flexible and less complicated to configure than an access list.. of the router. There is always an implicit deny all at the end of the access list that can’t be seen. How- ever, although the access list has been created, we need to filter all of the BGP...

Route maps. Which of the following can be used to avoid creating a full-mesh net- work? (Choose all that apply.). Route maps C. Which of the following commands shows the configured peer BGP routers and the current connection state?. Which of the following is not a way of managing routes advertised by BGP routers?. You can lengthen the AS-PATH length...

If you then convert these 20 bits back into decimal, you will have the address of the summarized route.. The area-id parameter in the area area-id virtual-link router-id command refers to the ID of the transit area. The UPDATE message type is used to advertise topology updates and changes. The NOTIFICA- TION message type is used to advertise errors. Route...

The evolution of the floating line was observed by monitoring the current consumption of the circuit over time. This evolution influences the logic behavior of the floating line since its interpretation changes from logic 1 to logic 0 after few seconds. Observation of quiescent current consumption of the circuit I DDQ. In such situation, the relative importance of the de-...

Obviously, such a domain must not be considered from the point of view of the optimization process.. The Global ADI represents the complete domain of the unpredictable parameter for which the defect can be detected considering the given test technique. On the example, the G-ADI represents the complete domain of the bridge resistance that can be detected by the input...
