Chapter 4: V-Switch Configuration 67
Adding an IP Route
You can enable communications to networks outside of your LAN by
configuring an IP routing path. This allows volume access to hosts located
on external networks. Use the CLI command ip route add to add an IP
routing path to your V-Switch. If you are working in a V-Switch cluster,
you must configure the IP route on both V-Switches in the V-Switch cluster.
For more information on V-Switch clusters, see “Introduction to V-Switch
Clusters,” page 72.
ip route add
You need four parameters to configure an IP routing path.

Example:
An IP routing path to Network D, IP 10.10.20.0, (IP mask 255.255.255.0) is
mapped from network port Eth2 through router gateway 30.30.20.20.
ip route add –dip 10.10.20.0 –dmask 255.255.255.0 –gw
30.30.20.20 –if eth2
Setting a Default Gateway
You can set a default gateway for Eth1 for working with your local
gateway. This gateway is used for any IP address not specified in the V-
Switch routing table. Use the CLI command ip route default to set
the default gateway IP address for Eth1. To change the default gateway,
repeat the command with the new default gateway IP address.
ip route default
You need one parameter to configure a default IP routing path.
