IP/IPVPN services with IEEE 802.1aq SPBB networks
Roger Lapuh, Paul Unbehagen · 2009
This document describes a compact method of using a IEEE 802.1aq Shortest Path Backbone Bridging SPBB network to natively enable and carry IP and IPVPN services for both unicast and multicast traffic on native Ethernet links. Further this documents the extensions to SPBB's control protocol, IS-IS, required to allow it to be a single mechanism for providing all these services types. On its own SPBB provides virtual Ethernet networks; utilizing IS-IS to create loop free Ethernet topologies that forward Ethernet traffic using a standard Ethernet header. This document shows how the same SPBB network can also be leveraged to provide IP based services.
