OpenVSwitch

Set up bridge patches through openvswitch bridges

This assumes you have tagged vlans 17 and 18 connected to the interface that identifies as eth1

Initially create the bridge that will have a port on the external network, also set vlans to trunk into openvswitch on external port

Fake bridge method

- This will create "fake" bridges vlan17 and vlan18 on primary bridge br-eth1 

sudo ovs-vsctl add-br br-eth1 \
    -- add-port br-eth1 eth1 \
    -- set port eth1 vlan_mode=trunk trunk=17,18 \
    -- add-br vlan17 br-eth1 17 \
    -- add-br vlan18 br-eth1 18

sudo dhclient vlan17 vlan18

At this point we should have ip addresses assigned to our ovs bridges via dhcp from the maas server.

Hybrid - Patch Bridge Method Intro

- This method uses patches to port between bridges
- In this initial example I create br-eth1 with vlans 17 and 18
- trunked in on eth1, a fake bridge is created and tagged for vlan17 on br-eth1
- and a second (non-fake) bridge br-vlan is created and tagged for vlan 18
- a patch is used to connect br-vlan and br-eth1 inturn giving br-vlan external connectivity through br-eth1's 
- port on physical interface eth1

sudo ovs-vsctl add-br br-eth1 \
    -- add-port br-eth1 eth1 \
    -- set port eth1 vlan_mode=trunk trunk=17,18 \
    -- add-br vlan17 br-eth1 17 \
    -- add-port br-eth1 patch-to-br-vlan \
    -- set Interface patch-to-br-vlan type=patch options:peer=patch-to-br-eth1

sudo ovs-vsctl add-br br-vlan \
    -- set port br-vlan tag=18 \
    -- add-port br-vlan patch-to-br-eth1 \
    -- set Interface patch-to-br-eth1 type=patch options:peer=patch-to-br-vlan

sudo dhclient vlan17 br-vlan
