Abstract

The signaling protocols used to establish point-to-point pseudowires

include type-length-value (TLV) fields that identify pseudowire

endpoints called attachment individual identifiers (AIIs). This

document defines AII structures in the form of new AII TLV fields

that support AII aggregation for improved scalability and Virtual

Private Network (VPN) auto-discovery. It is envisioned that this

would be useful in large inter-domain virtual private wire service

networks where pseudowires are established between selected local and

remote provider edge (PE) nodes based on customer need.
