Overview
This lab demonstrates how to use Segment Routing (SR) in a VPNv4/VPNv6 over IPv4/MPLS network. The VPN prefixes automatically leverage the SR information of their BGP next hop. SR applied to the MPLS data plane enables the ability to tunnel services, such as VPN, VPLS, and VPWS, from an ingress Provider Edge (PE) to an egress PE, without any protocol other than ISIS or OSPF. LDP and RSVP-TE signaling protocols are not required. By allocating one prefix segment per PE, the SR IGP control plane automatically builds the required MPLS forwarding constructs from any PE to any PE.
This lab requires familiarity with the Cisco® networking architecture and routing fundamentals.
