Explains building on the messages and procedures defined in IETF draft "BGP/MPLS IP Virtual Private Networks (VPNs)", this feature provides IPv6 L3VPNs (VPNv6) over an SRv6 network.
A IPv6 L3VPN over SRv6 is an MPLS VPN solution that
-
leverages Segment Routing over IPv6 (SRv6) to transport VPNv6 traffic between Provider Edge (PE) routers,
-
uses BGP to signal and carry service-specific Segment Identifiers (SIDs) as part of the VPN overlay, and
-
enables flexible, scalable IPv6-based Layer 3 VPN deployments across supported Cisco platforms.

IPv6 L3VPN over SRv6 |
Release 7.8.1 |
With this feature, the egress PE can signal an SRv6 Service SID with the BGP overlay service route. The ingress PE encapsulates the IPv4/IPv6 payload in an outer IPv6 header where the destination address is the SRv6 Service SID provided by the egress PE. BGP messages between PEs carry SRv6 Service SIDs as a means to interconnect PEs and form VPNs. |
