Segment Routing encodes the segment sequence representing the forwarding path in the header of the data packet, transmits it along with the data packet, and parses the segment sequence after receiving the data packet at the receiving end. If the segment ID at the top of the segment sequence is the current node, pop up the ID and proceed to the next step. If not, use the ECMP (Equal Cost Multiple Path) method to forward the data packet to the next node.

• A.False
• B.True
