The base TRILL (Transparent Interconnection of Lots of Links)
protocol provides optimal pair-wise data frame forwarding for Layer 2
intra-subnet traffic but not for Layer 3 inter-subnet traffic. 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. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
