IP Routing

Switch Administration

2p›F SmartCell ZX-250 IP routing performance is inadequate for routing between VLANS. If you need to create routes between VLANs on your SmartCell ZX-250, use a Cabletron recommended router equipped with an ATM interface. Consult Cabletron Customer Support for router product information.

For example,

Switch SW1 and the NMS are on an Ethernet network with the address 128.205.99.0.

The IP address of SW1’s Ethernet port is 128.205.99.254.

The IP address of SW1’s LANE client is 90.1.1.254.

The IP address of SW2’s LANE client is 90.1.1.33.

SW2 is not physically connected to the Ethernet network.

SW2 is connected to SW1 through PNNI, and are both part of the same emulated LAN.

To reach SW2 with the Ethernet-based NMS, define an IP route on SW2 that assigns SW1’s switch client as SW2’s default gateway to the network 128.205.99.0. Enter the following on SW2 (see Figure 4-3):

SmartCell ZX # add route

DestNetIP()

: 128.205.99.0

< address of the Ethernet network to reach

GatewayIP()

: 90.1.1.254

< IP address of SW1’s LANE client

SmartCell ZX #

 

Switch SW2 can communicate with the NMS on the Ethernet network. To see the route, enter the show route command on SW2.

2p›F The NMS must contain a route that specifies the Ethernet interface of the Ethernet connected switch as the gateway to the ELAN subnet.
