Introduction • Includes text on: • RBridge forwarding strategy • Data required to support this strategy • Procedures required to derive this data
Options Considered • Removed text on options considered • relative to RBridge forwarding at each hop • relative to STP “participation” roles
Definitions • Removed ambiguous use of “campus” • Replaced with acronym “CRED” • “Cooperating RBridges and Encapsulation Tunnels (Domain)” • Fixed definitions for • Designated RBridge • SPF • Other minor clarifications/corrections

Roles • Clarified the roles of Designated RBridge • In forwarding on and off of the CRED • In advertising MAC reachability • Clarified role/usage of forwarding table for the Ingress RBridge Tree (CFT-IRT
Still to be discussed • Inclusion of “pseudo-node” use • Too detailed for architecture? • Too protocol specific for architecture? • Remove distinctions of Hubs, Switches and Bridges in section 4 discussion and figures? • More inclusive Security statement • More the “job” of normative document (such as protocol specification? • Contrary to goals of the WG?
Next Steps • More comments? • At least a few more rounds of editing… • Accept as a WG document?
