In this document we present definitions of TRILL OAM messages.
Messages defined in this document follow a similar structure to IEEE
802.1ag messages. In this document, only the high level proposal on
using IEEE 802.1ag messaging is presented. The goal is to facilitate
discussion on feasibility of using IEEE 802.1ag messages for TRILL
OAM. Based on feedback from TRILL WG and IEEE 802.1 group, this
document may be further updated.
