Figure7-10 Routing in an FDDI/Ethernet Internetwork
For example, in the FDDI/Ethernet internetwork shown in Figure7-10, there
are parallel routes between jill and judy across relativelyfaster and slower
networks:
•Route 1 (across FDDI link):
jill➙bob-le0➙bob-pf➙sam-pf➙sam-le0➙judy
•Route 2 (across Ethernet link):
jill➙bob-le0➙bob-le1➙sam-le1➙sam-le0➙judy
An identical number of hops between the two stations exists regardless of the
route taken; therefore, routed may send all of the trafficacross the slower
Ethernet link in preference to the faster FDDI link.
