in one of the following two ways:

Replacing a source route bridge or router
To segment a congested ring without using new router ports, be sure that all
stations previously connected to a single router port are in the same virtual
ring (refer to Using SpeedView 2.1 for Windows). The router will continue
to view the network the same way it did before the rings were segmented.
To concentrate multiple, small ring segments into a router subnet and to free
router ports, be sure all segments are in the same virtual ring so that you can
group the entire virtual ring into a single router port. Be sure that the number
of devices in the virtual ring does not exceed the subnet size defined on the
router.
