Hedge 266: SR/MPLS

When most people think of segment routing (SR), they think of SRv6--using IPv6 addresses as segment IDs, and breaking the least significant /64 to create microsids for service differentiation. This is not, however, the only way to implement and deploy SR. The alternative is SR using MPLS labels, or SR/MPLS. Hemant Sharma joins Tom Ammon and Russ White to discuss SR/MPLS, why operators might choose MPLS over IPv6 SIDs, and other topics related to SR/MPLS. You can find Hermant's recent book on SR/MPLS here.
