The authors should elaborate on what makes them think so.
Let's observe that in order to encapsulate traffic in MPLS in 1000 node network and steer it north and south 1000 nodes need to be able to support MPLS (or for that matter RSVP-TE and IGP extensions - let's leave aside inter-area problems). Contrary if the desire is to steer traffic via north and south nodes from given ingress node to egress node only those 4 out of those 1000 nodes need to support segment routing. Non of the transit nodes needs to be SR aware. I think this makes the deployment and operational difference very clear. r. _______________________________________________ spring mailing list [email protected] https://www.ietf.org/mailman/listinfo/spring
