This lab will focus on SRv6 microsegment (uSID), an extension of the SRv6 architecture that leverages the SRv6 network programming architecture to encode several SRv6 micro-SID (uSID) instructions within a single 128-bit SID address. SRv6 uSID is an evolution and full replacement of MPLS technology in service provider networks. In this lab, you will configure a service provider network where only IPv6 routing is used to provide underlying reachability and SRv6 is used to provide overlay services.
