An interface is configured on a router for OSPF but the command "show router ospf neighbor" does not show any neighbors. Which of the following is NOT a possible cause?
Which of the following statements regarding OSPF routing updates on a point-to-point link is true?
Two IS-IS L1/L2 routers are in the same area on the same Ethernet segment. One of the routers is the DIS. How many adjacencies will be formed between them?
Click the exhibit button
The 192 168 3.0/24 network is learned on router R1 via IS-IS Given the OSPF configuration shown, and assuming that the OSPF adjacency between routers R1 and R3 is up, why is the 192 168.3.0/24 route not in router R3's route table? (Choose two)
Click the exhibit button. Assuming point-to-point links, which of the following statements is true?
Click on the exhibit.
Router R2 uses IS-IS to advertise the network 192.168.3.0/24 to R1. How can router R1 discard the route?
Click on the exhibit.
Router R2 uses OSPF to advertise the network 192.168.3.0/24 to router R1. A route policy has been configured to reject the route on router R1.
Why doesn't the route policy work?
Click on the exhibit.
A static route has been configured on router R1 to reach the PC at 139.120.121.2. What else is required to make the ping succeed?
Click on the exhibit.
192.168.3.1 is a loopback interface on router R2 and is distributed to OSPF area 0, but the ping fails from router R3. Which of the following is a possible solution to the problem?
Click on the exhibit.
OSPF router R2 has both point-to-point and broadcast interfaces and it is not a DR for any interfaces. Router R2 detects the link failure between itself and router R1.
Which of the following is correct?
Click on the exhibit.
OSPF is operational on all links in the network diagram, all links are the same cost, and all routers are configured with an ECMP value of 4. Router R4 advertises the prefix 192.168.3.0/24 into OSPF.
How many entries for prefix 192.168.3.0/24 will be in router R5's routing table?
Which of the following is a valid IPv6 address equivalent to 2001:0da8:0000:0000:0024:0000:4ab9:0300?
Click on the exhibit.
A service provider is deploying a 6 over 4 tunnel to connect a customer's corporate IPv6 network to all devices at the branch office as shown in the exhibit.
Which command is used to create the route to the branch office network on PE1?
Click on the exhibit.
Router R1 distributes its globally routed address and its loopbacks into IS-IS. Routers R2 and R4 have their globally routed addresses in IS-IS.
How many routes will router R4 have in its IPv6 route table?
Click on the exhibit.
Router R2 learns the networks shown from IS-IS. Router R2 is configured to redistribute routes from IS-IS to OSPF as shown. Assume the OSPF and IS-IS adjacencies are operational.
How many OSPF Type 5 LSAs will router R1 receive from router R2?
Click on the exhibit.
Examine the physical topology of the IS-IS network, the metrics of the links and the levels of the routers. All routers have a system address included in IS-IS.
Which of the following describes the route that router R4 will use to reach the system address of router R6?
A new router is added to a broadcast network. What is used by IS-IS as the tie breaker for selecting the DIS if the priorities are the same?
What command could be used to verify proper configuration of a static route in an Alcatel-Lucent 7750 SR router?
An OSPF router receives an update in which the sequence number, age, and checksum are the same as the entry already in the topological database. What action is taken by the router?
Click the exhibit button.
Two neighboring OSPF routers have exchanged the packets shown. What state is the adjacency in?
What acts as the tie breaker on an Alcatel-Lucent 7750 SR if the priorities are the same when IS-IS is electing a DIS?
What is the value of the protocol discriminator used to denote IS-IS protocol information?
How many bytes make up the system ID in an IS-IS NSAP address on the Alcatel-Lucent 7750 SR?
Which of the following is an optional parameter when configuring IS-IS protocol on a router?
Click the exhibit button.
Given the topology and the show commands, and assuming that router R2 advertises all of its loopbacks into OSPF, what is the correct router R1 configuration?
Click the exhibit button.
Router R2 advertises the network 192.168.3.0/24 to router R1 via OSPF. A route policy has been constructed to discard the route on router R1; however, it is not working. What is the problem?
Static routing will be used in a network between a corporate head office, with many connected networks, and a branch office, with one connection to the head office. Which of the following best describes the likely configuration?
Which type of IS-IS router is summarization most likely to be configured on?
Click the exhibit button.
What is the command to configure a static route on the Alcatel-Lucent 7750 SR router R1 to reach the network behind router R2?
