Convert DVR configuration been built in RDO Liberty DVR Neutron workflow on CentOS 7.1 in the same way as it was done in ([ 1 ]) .
Setup configuration
- Controller node: Nova, Keystone, Cinder, Glance,
Neutron (using Open vSwitch plugin && VXLAN )
- (2x) Compute node: Nova (nova-compute),
Neutron (openvswitch-agent,l3-agent,metadata-agent )
*****************************************************
On Controller and first Compute Node
*****************************************************
# yum install keepalived
*************************************************************************
Stop and disable neutron-l3-agent on Second Compute Node
Update /etc/neutron/neutron.conf as follows
**************************************************************************
[DEFAULT]
router_distributed = False
l3_ha = True
max_l3_agents_per_router = 2
*****************************************************************
Switch agent_mode to legacy on all nodes
Update /etc/neutron/plugins/ml2/openvswitch_agent.ini
*****************************************************************
[agent]
enable_distributed_routing = False
All nodes restart
************************************************************
Create HA router belongs tenant demo
