Sub-interface VLAN YANG Data Models
draft-ietf-netmod-sub-intf-vlan-model-00
Abstract
This document defines YANG modules to add support for classifying
traffic received on interfaces as Ethernet/VLAN framed packets to
sub-interfaces based on the fields available in the Ethernet/VLAN
frame headers. These modules allow IETF forwarding protocols (such
as IPv6 and VPLS) to interoperate with VLAN tagged traffic orginated
from an IEEE 802.1Q compliant bridge. Primarily the classification
is based on VLAN identifiers in the 802.1Q VLAN tags, but the model
also has support for matching on some other layer 2 frame header
fields and is designed to be extensible to match on other arbitrary
header fields.
The model differs from an IEEE 802.1Q bridge model in that the
configuration is interface/sub-interface based as opposed to being
based on membership of an 802.1Q VLAN bridge.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."
This Internet-Draft will expire on July 24, 2017.
