What is Segment Routing (SR) and how does it differ from MPLS?
Correct! Well done.
Incorrect.
The correct answer is B) An architecture encoding the path as a stack of segments (instructions) in the packet header, eliminating per-flow state in transit nodes unlike MPLS-TE
B
Correct Answer
An architecture encoding the path as a stack of segments (instructions) in the packet header, eliminating per-flow state in transit nodes unlike MPLS-TE
Explanation
SR-MPLS: segments are MPLS labels. SRv6: segments are IPv6 addresses in a Routing Extension Header. Eliminates LDP/RSVP-TE for path setup. Transit nodes just pop/swap labels with no per-flow state.
