15 Deploying and configuring OMIVV in a dual-NIC environment
2.1 Configure dual-NIC with multiple subnets
The following section describes the dual-NIC with Multi-Subnets configuration.
The following image is an example where the OMIVV appliance is connected with two different isolated
networks with multiple subnets for out-of-band network. The vSphere network is configured with DHCP server
where the IP and DNS information are provided by the DHCP server whereas the out-of-band network is
configured with static IP, which also has multiple subnetworks.
Figure 12: Dual-NIC configuration with multiple subnets
Figure 13: Routing table and manual IP configuration with IP, netmask and gateway
Here the default gateway is assigned to 100.96.22.1. Any packets sent to 192.168.11.0 will be sent to
gateway 192.168.11.1 and any packets sent to 100.96.22.0 or any other will be forwarded gateway
100.96.22.1.
However, packets to be sent to 192.168.50.x subnet of private network will be forwarded to default gateway
which is 100.96.22.1 due to which the packets are sent to wrong destination or dropped as there is no
destination host in vSphere network.
To avoid this issue we need to configire the routes in the network configuration tab by providing subnet, mask,
and its gateway to pass the packets as shown in the following images:
