Configuring additional gateways for vmkernel ports on an ESXi host

To configure a second gateway for the management network:
Open a console to the ESX or ESXi host.

  Run this command:

• esxcfg-route -a target network  netmask gateway 

For example, to add a route to 192.168.100.0 network through 192.168.0.1
 run one of these command:

• esxcfg-route -a 192.168.100.0/24 192.168.0.1
• esxcfg-route -a 192.168.100.0 255.255.255.0 192.168.0.1

The command esxcfg-route -l lists the current routing table. VMware KB article
