OpenVRR

OpenVRR is a solution to improve kernel routing and performance by openvswitch.

As a Gateway

                        +---------+
    [PCa] -- vlan10 --> | OpenVRR | <-- vlan20 --- [PCb]
                        +---------+

The PCa access to OpenVRR via vlan 10, and as a vlan 10 subnet gateway.

vrrcli interface vlan add --tag 10 --interface eth1
vrrcli interface create --name vlan10

ifconfig vlan10 192.168.1.1/24

The PCb access to OpenVRR via vlan 20, and as a vlan 20 subnet gateway..

vrrcli interface vlan add --tag 20 --interface eth2
vrrcli interface create --name vlan20

ifconfig vlan20 192.168.2.1/24
