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.
