To enable the LDP-over-RSVP feature, which of the following configurations is NOT required on an Alcatel-Lucent 7750 SR?
Click on the exhibit.
An LDP tunnel is established on R1-R2-R4-R6 because the link between routers R3 and R6 is down. With the LDP-IGP Sync feature enabled, what happens immediately after the link is restored?
Click on the exhibit. After the Isp-ping command is executed, which of the following best describe the router's action?
Which of the following configurations allow a router to periodically attempt to move LSP traffic to a better path, if the head end can find one?
Which of the following about Alcatel-Lucent 7750 SR command "oam Isp-trace prefix" is FALSE?
Which one of the following statements regarding RSVP LSP configuration is true?
LDP is enabled on both ends of a point-to-point link, but the "show router Idp status" command indicates that LDP is operationally down. The Oper Down Reason field shows the message "systemIpDown." What might cause this condition?
What MPLS function should be performed by a router that receives a data packet containing an MPLS label value of 3?
Fill in the blanks: The device at the beginning of an LSP is referred to as the_________, and the device at the end of an LSP is referred to as the___________.
An Alcatel-Lucent 7750 SR enabled with LDP has multiple equal cost paths to a given FEC. After ECMP is enabled, which of the following is FALSE?
Click on the exhibit.
This policy is applied as an LDP export policy. In addition to the FECs learned from its neighbors, which FECs now appear in the router's LIB?
Click on the exhibit.
All links are operationally up initially. When the link between routers R4 and R6 goes down, what will router R1 do?
Click on the exhibit.
An LSP path is established on router R1 toward router R6. If the link between routers R4 and R6 goes down, which of the following is the quickest way for service recovery?
Click on the exhibit.
An LSP traverses the path R1-R2-R3-R6 and facility fast reroute is enabled. If the protected LSP carries one transport label and one service label, how many labels will be on the bypass tunnel if router R2 fails?
Click on the exhibit.
Both Path-1 and Path-2 are down. If Path-2 becomes available again, how does the headend router select the secondary LSP path?
Click on the exhibit.
A fully loose LSP MtoR6" is enabled with FRR protection. All links have the same cost. After the link between R2 and R4 goes down, FRR protection repairs the LSP and traffic traverses on R1-R2-R7-R8-R4-R6. By default, which of the following about this LSP on an Alcatel-Lucent 7750 SR is FALSE?
Click on the exhibit.
An LSP path is established on router R1 toward router R6. After router R4 detects that the link between routers R4 and R6 goes down, which of the following will affect the failure propagation time?
Click on the exhibit button below.
LSP "toR8-5" requests fast reroute protection on the primary loose path. What could be done to remove the Failure Code shown?
Which of the following statements regarding LDP-over-RSVP are true? (Choose two)
If an LSP's loose primary path includes the statement "include green" and "exclude red;" how does CSPF choose the LSP's path?
Which of the following commands may only be used on the head end router to verify the status of an LSP named "LSP 1"? (Choose two)
Click on the exhibit button below.
Given the following fast reroute protected LSPs:
-LSP1.R1-R4-R5-R3
-LSP2.R1-R4-R5-R2
Which routers become bypass tunnel PLRs? Choose two answers
Which of the following reservation styles can be used to prevent both the primary and secondary paths from booking resources on a common link?
Which of the following statements regarding RSVP path messages on an Alcatel-Lucent SR is true?
Which of the following prerequisites must you configure on a router to enable LDP-over-RSVP support? (Choose two)
You wish to advertise LDP labels for all local networks; which is the most effective policy statement to use?
