MPLS and Segment Routing

What is the function of a segment routing mapping server?

  • A It advertises a local SID mapping policy to all of the mapping clients
  • B It works with IGP instances to calculate the prefix-SIDs in the absence of a mapping policy
  • C It selects multiple mapping entries to create overlapping active mapping policies
  • D It reads and translates remotely received SIDs from other mapping servers to create SID mapping entries
Explanation

A Segment Routing Mapping Server creates a local prefix-to-SID mapping policy from configured entries and advertises that local SID-mapping policy to mapping clients. The policy’s entries are non-overlapping; mapping clients receive and parse the server’s advertised mappings.
