SRv6 Deployment Options

When deciding to migrate a network from existing data-plane technologies (e.g. MPLS, SR-MPLS or overlay encapsulations such as VXLAN) to SRv6, common questions involve how to perform the migration, how to minimize impact to the existing network and what techniques are available to support a smooth transition. This document presents various deployment and migration options for networks evolving toward SRv6 from prior transport or overlay technologies.
