Segment Routing Traffic Engineering

First, you need to remember MPLS-Traffic engineering operation.

MPLS-traffic engineering requires four steps, as shown below, for its operation.

  1. Link information such as bandwidth, IGP metric, TE metric, and SRLG is flooded throughout the IGP domain by the link state protocols.
  2. The path is calculated either with CSPF in a distributed manner  or with offline tools as a centralized fashion.
  3. If a suitable path is found, it is signalled via RSVP-TE and the RSVP assigns the label for the tunnels.
  4. The traffic is placed in the tunnels.
