Static configurations
—Static configurations are independent from the VCF fabric topology
and can be directly executed. The following are examples of static configurations:
#STATICCFG
#
clock timezone newyork add 08:00:00
#
lldp global enable
#
stp global enable
#
•
Dynamic configurations
—Dynamic configurations are dependent on the VCF fabric topology.
The device first obtains the topology information and then executes dynamic configurations.
The following are examples of dynamic configurations:
#
interface $$_underlayIntfDown
port link-mode route
ip address unnumbered interface LoopBack0
ospf 1 area 0.0.0.0
ospf network-type p2p
lldp management-address arp-learning
lldp tlv-enable basic-tlv management-address-tlv interface LoopBack0

Automated overlay network deployment
Automated overlay network deployment covers VXLAN deployment and EVPN deployment.
Automated overlay network deployment is mainly implemented through the following features of
Neutron:
•
Layer 2 agent (L2 agent)
—Responds to OpenStack events such as network creation, subnet
creation, and port creation. It deploys Layer 2 networking to provide Layer 2 connectivity within
a virtual network and Layer 2 isolation between different virtual networks.
•
Layer 3 agent (L3 agent)
—Responds to OpenStack events such as virtual router creation,
interface creation, and gateway configuration. It deploys the IP gateways to provide Layer 3
forwarding services for VMs.
For the device to correctly communicate with the Neutron server through the RabbitMQ server, you
need to configure the RabbitMQ server parameters. The parameters include the IP address of the
RabbitMQ server, the username and password to log in to the RabbitMQ server, and the listening
port.
Configuration restrictions and guidelines
VCF fabric is supported only by devices that operate in standalone mode.
Typically, the device completes both automated underlay network provisioning and automated
overlay network deployment by downloading and executing the template file. You do not need to
manually configure the device by using commands. If the device needs to complete only automated
overlay network deployment, you can use related commands in "
Configuring automated overlay network deployment
." No template file is required.
