SANRAD V-Switch manual Adding an IP Route, Setting a Default Gateway

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.

SWITCH PARAMETER DEFINITION STATUS EXAMPLE

-dip	DESTINATION IP	IP OF HOST	MANDATORY
		NETWORK
-dmask	DESTINATION	IP MASK OF HOST	MANDATORY
	MASK	NETWORK
-gw	GATEWAY IP	IP ADDRESS OF	MANDATORY
	ADDRESS	THE GATEWAY
		ROUTER

10.10.20.0

255.255.255.0

30.30.20.20

-if

INTERFACE	NETWORK PORT TO	MANDATORY	eth2
ALIAS	OPEN
	COMMUNICATION
	THROUGH

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.

SWITCH	PARAMETER	DEFINITION	STATUS	EXAMPLE
-gw	GATEWAY	IP ADDRESS OF	MANDATORY	20.20.10.20
		DEFAULT GATEWAY
