Figure 7-10 Routing in an FDDI/Ethernet Internetwork

For example, in the FDDI/Ethernet internetwork shown in Figure 7-10, there

are parallel routes between jill and judy across relatively faster 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 traffic across the slower

Ethernet link in preference to the faster FDDI link.
