Abstract
A shared infrastructure tunnel binds multiple Ethernet Virtual Private Network instances that depend on a common transport path between two provider edge nodes into a single named operational group. An advertising node attaches a grouping identifier to per-instance route advertisements. A receiving node builds a group object holding the membership set, a binding to primary and backup transport resources, and a state machine. One liveness session monitors the group in place of one session per instance, and each group state transition is applied atomically and identically to every member at both nodes without generating per-instance control plane messages. An individual member may be withheld from service without disturbing the group. The identifier is confined to the control plane and appears in no data plane header, leaving encapsulation and forwarding unchanged, and a node that does not recognize the identifier reverts automatically to per-instance behavior.
