To avoid this situation, set up a static route that forces the traffic between jill
and judy to pass over the FDDI link; however, static routing is not
recommended in a network beyond a few nodes in size. For efficient IP routing
in large FDDI/Ethernet networks, use a routing package that provides routing
metrics in addition to hop count (for example, gated, public domain software
available by the Center for Theory and Simulation in Science at Cornell
University).
To improve the end-to-end system performance across the boundary between
the networks, you may need to alter the default MTU for the FDDI network
(see "Performance Across Bridges" on page 25) or to disable the MTU path
discovery feature (see "Improving Performance" on page 27).
