QuestionQ31

Open Shortest Path First (OSPF)

You are a network architect designing an entirely new network and plan to deploy RSVP LSPs. You are deciding whether to use OSPF or IS-IS as the interior gateway protocol.

In this scenario, which two statements about IGP traffic-engineering extensions in an RSVP network are correct?

Choose two
  • A You must explicitly configure IS-IS to carry traffic engineering extensions.
  • B You must explicitly configure OSPF to carry traffic engineering extensions.
  • C In OSPF, traffic engineering extensions are enabled by default.
  • D In IS-IS, traffic engineering extensions are enabled by default.
Explanation

In Junos, IS-IS traffic-engineering support is enabled by default. OSPF traffic-engineering support is disabled by default and must be explicitly enabled with the OSPF traffic-engineering configuration, allowing it to advertise the TE information used for RSVP constrained-path LSP computation.
