QuestionQ256

Routing Policy and Manipulation

Which feature delivers service independence in service-provider networks?

  • A node SID that identifies the network device
  • B prefix SID that contains router hops toward the destination
  • C adjacency SID that represents a path between the routers
  • D binding SID that is used to stitch different domains
Explanation

A Binding SID is bound to an SR Policy and hides the policy’s underlying SID list from users of that policy. Traffic can be steered using the stable Binding SID even when the internal path or policy changes, providing service independence.
