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.

Hedge 265: Out of Band Networks
Out of band management networks were once more common than they are today. Should we go back to building out of band management networks? Should out of band management networks be virtual or physical? How can we sell out of band management networks to the folks paying the bills? Daryll Swer joins Tom Ammon and Russ White to discuss the importance of OOB management.

Hedge 262: Stealthy BGP Attacks
Many providers count on detection in the global routing table to discover and counter BGP route hijacks. What if there were a kind of BGP hijack that cannot be detected using current mechanisms? Henry Birge-Lee joins Tom Ammon and Russ White to discuss a kind of stealthy BGP attack that avoids normal detection, and how we can resolve these attacks.
