MPLS and Segment Routing

What is one characteristic of a segment routing mapping server?

  • A It serves multiple VRFs.
  • B It applies SID mappings from one IGP instance to another IGP instance.
  • C It must be placed in the core of the network.
  • D It must have an IGP adjacency.
Explanation

A segment routing mapping server advertises SID mappings through the normal IGP advertisement mechanism, so it needs an IGP adjacency to the network. Its placement in the network is not inherently important, it does not support VRFs in this implementation, and SID mappings learned through one IGP instance cannot be used by another instance.
