The Network Configuration Manager allows you to find
the optimal route between machines on different Token-Ring rings:
yes
Use All Routes Explorers (AREs) to discover the
optimal route.
This is the default.
no
Do not try to find the optimal route. Do not use AREs.
It is usually desirable to use ARE explorer frames to
discover routes because they find
the fastest route between two points and store the information
in the Token-Ring source routing table
for future transmissions.
However, in large networks,
using AREs can cause
additional network traffic and slow down the network.
If minimizing frame traffic is desirable,
you may not want to optimize routing.
