Durrani, P.

A centralized gateway solution is typically used for Layer 3 inter-subnet traffic forwarding but has the following issues: 1. Sub-optimum forwarding paths for inter-subnet traffic. 2. A centralized gateway that may need to support a very large number of gateway interfaces in a Data Center, one per tenant per Data Label used by that tenant, to provide interconnect functionality for all the Layer 2 Virtual Networks in a TRILL campus. 3. A traffic bottleneck at the gateway. This document specifies an optional TRILL distributed gateway solution that resolves these centralized gateway issues. This document is a product of the Transparent Interconnection of Lots of Links Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements.
