Neutron is a type of OpenStack services used to manage all virtual networking infrastructures (VNIs) in an OpenStack environment. It provides virtual network services to the devices managed by OpenStack computing services. It allows tenants to create advanced virtual services, such as a firewall (FW), load balancer (LB), and virtual private network (VPN).

SeerEngine-DC Neutron plug-ins are developed for the SeerEngine-DC controller based on the OpenStack framework. The following SeerEngine-DC Neutron plug-ins are available:

· SeerEngine-DC Neutron Core plug-ins—Includes networks, subnets, routers, and ports and provides tenants with core basic network communication capabilities.

· SeerEngine-DC Neutron L3_Routing plug-in—Allows tenants to forward traffic to each other at Layer 3.

· SeerEngine-DC Neutron FWaaS plug-in—Allows tenants to create firewall services.

· SeerEngine-DC Neutron LBaaS plug-in—Allows tenants to create LB services.

· SeerEngine-DC Neutron VPNaaS plug-in—Allows tenants to create VPN services.

The SeerEngine-DC Neutron plug-ins allow deployment of the network configuration obtained from OpenStack through REST APIs on the SeerEngine-DC controller, including tenants' networks, subnets, routers, ports, FW, LB, and VPN settings.

CAUTION:

To avoid service interruptions, do not modify the settings issued by the cloud platform on the controller, such as the virtual link layer network, vRouter, and vSubnet settings after the plug-ins connect to the OpenStack cloud platform.

Installing OpenStack plug-ins

The SeerEngine-DC Neutron plug-ins can be installed on different OpenStack versions. The installation package varies by OpenStack version. However, you can use the same procedure to install the Neutron plug-ins on different OpenStack versions. This document uses OpenStack Ocata as an example.

The SeerEngine-DC Neutron plug-ins are installed on the OpenStack control node.

Setting up the basic environment

Before installing SeerEngine-DC Neutron plug-ins on the OpenStack control node, set up the basic environment on the node.

To set up the basic environment:

1. Update the software source list, and then download and install the Python tools.

The following uses commands on a CentOS operating system as an example.

[root@localhost ~]# yum clean all

[root@localhost ~]# yum makecache

[root@localhost ~]# yum install –y python-pip python-setuptools

2. Install runlike.

[root@localhost ~]# pip install runlike

3. Access the neutron_server container and edit the /etc/hosts file. Add the following information to the file.

¡ IP and name mappings of all hosts in this OpenStack environment. To obtain this information, access the SeerEngine-DC controller and select Provision > Domains > Hosts.

¡ IP and name mappings of all leaf, spine, and border devices in this scenario. To obtain this information, access the SeerEngine-DC controller and select Provision > Inventory > Devices.

Installing the SeerEngine-DC Neutron plug-ins

Obtaining the SeerEngine-DC Neutron plug-in installation package

The SeerEngine-DC Neutron plug-ins are included in the SeerEngine-DC OpenStack package. Obtain the SeerEngine-DC OpenStack package of the required version and then save the package to the target installation directory on the server or virtual machine.

Alternatively, transfer the installation package to the target installation directory through a file transfer protocol such as FTP, TFTP, or SCP. Use the binary transfer mode to prevent the software package from being corrupted during transit.

Installing the SeerEngine-DC Neutron plug-ins on the OpenStack control node

1. Create the startup scripts for the neutron-server and h3c-agent containers.

[root@localhost ~]# runlike neutron_server>docker-neutron-server.sh

[root@localhost ~]# cp docker-neutron-server.sh docker-h3c-agent.sh

[root@localhost ~]# sed -i 's/neutron-server/h3c-agent/g' docker-h3c-agent.sh

[root@localhost ~]# sed -i 's/neutron_server/h3c_agent/g' docker-h3c-agent.sh

2. Modify the neutron.conf configuration file.

a. Use the vi editor to open the neutron.conf configuration file.

[root@localhost ~]# vi /etc/kolla/neutron-server/neutron.conf

b. Press I to switch to the insert mode, and modify the configuration file. For information about the parameters, see "neutron.conf."

For Pike and Rocky plug-ins:

[DEFAULT]

core_plugin = ml2

service_plugins = h3c_l3_router,firewall,lbaasv2,vpnaas,qos,h3c_vpc_connection

[service_providers]

service_provider=FIREWALL:H3C: networking_h3c.fw.h3c_fwplugin_driver.H3CFwaasDriver:default

service_provider=LOADBALANCERV2:H3C: networking_h3c.lb.h3c_lbplugin_driver_v2.H3CLbaasv2PluginDriver:default

service_provider=VPN:H3C: networking_h3c.vpn.h3c_vpnplugin_driver.H3CVpnPluginDriver:default

service_provider=VPC_CONNECTION:H3C:networking_h3c.vpc_connection.h3c_vpc_connection_driver_match_plugin.H3CVpcConnectionMatchPluginDriver:default

IMPORTANT:

· For the Pike plug-ins, when the load balancer supports multiple resource pools of the Context type, you must preprovision a resource pool named dmz or core on the controller, and then change the value of the service provider parameter to LOADBALANCERV2:DMZ:networking_h3c.lb.h3c_lbplugin_driver_v2.H3CLbaasv2PluginDMZDriver:default or LOADBALANCERV2:CORE:networking_h3c.lb.h3c_lbplugin_driver_v2.H3CLbaasv2PluginCOREDriver:default accordingly.

· If you set the value for vRouter interconnection to vpc_connection when configuring the service_plugins parameter, you must set the value of the corresponding service_provider parameter to VPC_CONNECTION:H3C:networking_h3c.l3_router.h3c_vpc_connection_driver.H3CVpcConnectionDriver:default.

· For the Pike plug-ins, if deployment of firewall policies and rules takes a long time, you can change firewall in the value of the service_plugins parameter to fwaas_h3c.

For Ocata plug-ins:

[DEFAULT]

core_plugin = ml2

service_plugins = h3c_sdnplugin.l3_router.h3c_l3_router_plugin.H3CL3RouterPlugin,firewall,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2,vpnaas,qos

[service_providers]

service_provider=FIREWALL:H3C:h3c_sdnplugin.fw.h3c_fwplugin_driver.H3CFwaasDriver:default

service_provider=LOADBALANCERV2:H3C:h3c_sdnplugin.lb.h3c_lbplugin_driver_v2.H3CLbaasv2PluginDriver:default

service_provider=VPN:H3C:h3c_sdnplugin.vpn.h3c_vpnplugin_driver.H3CVpnPluginDriver:default

[qos]

notification_drivers = message_queue,qos_h3c

IMPORTANT:

The QoS feature will not operate correctly if you configure the database connection in configuration file neutron.conf as follows:

[database]

connection = mysql://…

This is an open source bug in OpenStack. To prevent this problem, configure the database connection as follows:

[database]

connection = mysql+pymysql://…

The three dots (…) in the command line represents the neutron database link information.

IMPORTANT:

· In the neutrone_server configuration directory (/etc/kolla/neutron-server/), you can configure the service_provider parameter for a service once only. If you have configured the service_provider parameter for the firewall service in the neutron.conf configuration file, do not configure the service_provider parameter in the fwaas_driver.ini file. This rule applies also to the LBaaS and PNaaS services.

· For h3c_agent to load the driver correctly, change the FWaaS driver value in the /etc/kolla/neutron-server/fwaas_driver.ini file to networking_h3c.fw.h3c_fwplugin_driver.H3CfwaasDriver.

CAUTION:

· Services might be interrupted during the SeerEngine-DC Neutron plug-ins upgrade procedure. Make sure you understand the impact of the upgrade before performing it on a live network.

· The plug-ins settings will not be restored automatically after an upgrade in the Kolla environment. Before an upgrade, back up the settings in the /etc/kolla/neutron-server/neutron.conf and /etc/kolla/neutron-server/ml2_conf.ini configuration files. After the upgrade, modify the parameter settings according to the configuration files to ensure configuration consistency before and after the upgrade.

To upgrade the SeerEngine-DC Neutron plug-ins, just install the new version of the plug-ins. For information about installing the SeerEngine-DC Neutron plug-ins, see "Installing the SeerEngine-DC Neutron plug-ins."

(Optional.) Configuring the metadata service for network nodes

OpenStack supports obtaining metadata from network nodes for VMs through DHCP or L3 gateway. H3C supports only the DHCP method. To configure the metadata service for network nodes:

1. Download the OpenStack installation guide from the OpenStack official website and follow the installation guide to configure the metadata service for the network nodes.

2. Configure the network nodes to provide metadata service through DHCP.

a. Use the vi editor to open configuration file dhcp_agent.ini.

[root@network ~]# vi /etc/kolla/neutron-dhcp-agent/dhcp_agent.ini

b. Press I to switch to the insert mode, and modify configuration file dhcp_agent.ini as follows:

[DEFAULT]

force_metadata = True

Set the value to True for the force_metadata parameter to force the network nodes to provide metadata service through DHCP.

c. Press Esc to quit insert mode, and enter :wq to exit the vi editor and save the dhcp_agent.ini configuration file.

3. Restart the dhcp-agent container.

[root@network ~]# docker restart neutron_dhcp_agent

FAQ

The Python tools cannot be installed using the yum command when a proxy server is used for Internet access. What should I do?

Configure HTTP proxy by performing the following steps:

1. Make sure the server or the virtual machine can access the HTTP proxy server.

2. At the CLI of the CentOS system, use the vi editor to open the yum.conf configuration file. If the yum.conf configuration file does not exist, this step creates the file.

[root@localhost ~]# vi /etc/yum.conf

3. Press I to switch to the insert mode, and provide HTTP proxy information as follows:

¡ If the server does not require authentication, enter HTTP proxy information in the following format:
proxy = http://yourproxyaddress:proxyport

¡ If the server requires authentication, enter HTTP proxy information in the following format:
proxy = http://yourproxyaddress:proxyport
proxy_username=username
proxy_password=password

Table 4 describes the arguments in HTTP proxy information.
