Method and system for support of spanning tree peering and tunneling in a flood domain

A method for support of spanning tree peering and tunneling with a plurality of flood domains comprising:

• configuring a first customer edge port (CEP) to peer spanning tree protocol (STP) data units across a provider network, the first CEP communicatively coupled to a customer network, a first flood domain, and a second flood domain, the first flood domain and second flood domain each comprising one or more provider network ports associated with the provider network;
• receiving a first data unit at the first CEP;
• transmitting the first data unit to a first STP processing instance associated with the first CEP;
• determining whether the first data unit is associated with the first flood domain or the second flood domain;
• forwarding the first data unit to the determined flood domain;
• configuring a second CEP to tunnel STP data units across the provider network, the second CEP communicatively coupled to the customer network and the first flood domain;
• receiving a second data unit at the second CEP;
• and
• forwarding the second data unit to the first flood domain.
