This document provides a description of Split Multi-Link Trunking
(SMLT) SMLT is an architecture for reliable and redundant Layer 2
networks, which allows the full usage of all provisioned links that
are dual-homing into a pair of aggregation devices in a MAC-bridged
network. Multi-Link Trunking (MLT) is a link-aggregation mechanism
similar to IEEE 802.3ad without the LACP(Link Aggregation Control
Protocol). Typical redundant Ethernet networks consist of wiring
closet (edge) switches dual-homed to network center aggregation
(core) switches in a building or campus. Similarly, in carrier and
ISP environments, CPE devices may be dual-homed to two SMLT
aggregation switches at a Service ProviderĘs point of presence
(POP). Traditionally, when a loop is created in the Layer 2 network
by dual-homing devices, Spanning Tree Protocol must block one of the
redundant network paths. SMLT avoids this by allowing all aggregated
paths in a dual-homed switch configuration to be active and
forwarding traffic simultaneously as well as providing very fast
traffic fail-over in the event of a link failure.

up into multiple messages), so check your local documentation on
how to manipulate these messages.
