You are asked to configure an LSP which uses the OSPF link state database for path computations. Which two statements are correct in this scenario? (Choose two.)

Question

Options

• AYou must use the no-cspf parameter in the label-switched-path configuration.
• BTraffic engineering extensions ate enabled by default In OSPF.
• CTraffic engineering extensions are not enabled by default in OSPF.
• DYou must use the policing parameter in the label-switched-path configuration.

• A
  80% (37)
• B
  7% (3)
• D
  13% (6)

Explanation

In Junos OS, traffic engineering extensions for OSPF, which are required for an LSP to use the OSPF link state database for path computations, are not enabled by default. They must be explicitly enabled in the OSPF configuration. Therefore, answer C is correct. Answer B is incorrect and contradicts C. The 'no-cspf' command would disable CSPF (Constrained Shortest Path First), which is used for path computations in MPLS traffic engineering, so it should not be used if you want the LSP to utilize OSPF's link state database for path computations. Therefore, answer A is incorrect. The 'policing' parameter is not relevant to enabling traffic engineering extensions in OSPF, so answer D is incorrect.
