Introduction to segment routing

Which of these statements concerning Multi-Protocol Label Switching networks is FALSE?

  • A MPLS uses a signaling protocol to exchange labels between routers.
  • B An LSR forwards data based on the MPLS labels.
  • C An LSP is a bi-directional tunnel that uses MPLS labels to forward data.
  • D The data is transparently carried from end to end.
Explanation

An MPLS Label Switched Path (LSP) is a directed path through label switching routers. Bidirectional communication normally uses separate LSPs for each direction, rather than one inherently bi-directional MPLS tunnel. RFC 3031 defines an LSP as a sequence of routers followed by packets in a forwarding equivalence class.
