A communications network is operated by providing a plurality of redundant
links between a first network node and a second network node. A first
identifier is associated with a first one of the plurality of redundant
links and a second identifier is associated with a second one of the
plurality of redundant links. The first and second identifiers are
associated with the regulatory constraint. Traffic that is marked with
the first identifier is routed to the first one of the plurality of
redundant links and traffic that is marked with the second identifier is
routed to the second one of the plurality of redundant links so that
operation of the communications network is in compliance with the
regulatory constraint.
