Figure 4-6 Switches that ATM Administrator cannot reach through Ethernet

Figure 4-7 is a diagram of the ATM and Ethernet connectivity of the network map shown in Figure 4-6. Notice that the
generic switches, 90.1.1.20 (Switch 4) and 90.1.1.24 (Switch 5), are not connected to the Ethernet network. As a result,
switches 4 and 5 do not have direct access to the NMS, and the NMS (using an Ethernet connection) does not know
how to reach the subnet 90.0.0.0, which is Switches 4 and 5's ELAN.

This connectivity problem can be fixed by creating routes between the NMS and the non-Ethernet connected switches:
Add a route on the NMS that specifies the gateway to 90.0.0.0 as the Ethernet interface of a switch
1.
that has connectivity to both Ethernet and the ATM ELAN.
