IS-IS is enabled on the link between nodes A
and C. Between B and D, you cannot configure
SPB on the MLT if it assigned with an SMLT
ID. Once the SMLT ID is removed, then SPB
can be enabled on the MLT.

This diagram illustrates a common SMLT Full
Mesh topology. Each switch has a local SMLT
MLT defined with two Ethernet port members.
When migrating this topology to SPB, IS-IS
must not be enabled on the MLT instance, but,
on the individual Ethernet ports which
constitute it. Please note that the switches can
only be ERS 8800 or VSP 9000.
