Note:ZStack Private Cloud allows you to create multiple L3 networks by using
an L2 network. However, we do not recommend to do so unless you have
special business requirements.
Click the
Plus sign (⊕) under the L2 Network field. Then,
the Select L2 Network page is displayed on the
right. This page has the following two tabs:
Default: Display a list of L2 networks that
do not have an L3 network attached in the current zone.
All: Display a list of all L2 networks in
the current zone, including the L2 networks that have or not
have an L3 network attached.
Stop DHCP server: Choose whether
to enable the DHCP service.
Note:
By default, this checkbox is not selected, indicating that the
DHCP service is enabled, and IP addresses will be automatically
allocated to VM instances. In this case, you can customize a
DHCP IP address, or let the system randomly specify a DHCP IP
address.
If selected, the DHCP service will be disabled, indicating that
VM instances that use this network cannot obtain IP addresses
automatically, and need to be configured manually with IP
addresses. In this case, you cannot customize the DHCP IP
address. In addition, the system cannot randomly specify a DHCP
IP address.
网络类型：选择ARM云路由
云路由规格：选择已创建的ARM云路由规格
添加网络段：选择添加网络段方法：IP范围、CIDR
如选择IP范围，需设置以下内容：
Start IP: Enter a start IP
address for the network range, such as
172.20.108.100.
End IP: Enter an end IP
address for the network range, such as
172.20.108.200.
Netmask: Enter a netmask for
the network range, such as 255.255.0.0.
Gateway: Enter a gateway for
the network range, such as 172.20.0.1.
DHCP IP:
Optional. Enter a DHCP IP address as needed, such as
172.20.108.10.
Note:
If you create an L3 network and enable the
DHCP service for the first time, or if you add the
first IP range for the L3 network of the enabled
DHCP service, you can customize the DHCP IP
address.
If the L3 network has a DHCP IP address, you
cannot customize the DHCP IP address when you add
an IP range.
The DHCP IP address can be included or
excluded on the added IP range. However, the DHCP
IP address must be within the CIDR to which the
added IP range belongs, and must not be
occupied.
The IP range specified within the start IP
address and end IP address cannot contain IP
addresses of the link-local address
(169.254.0.0/16).
If not specified, the system will randomly
specify an IP address within the IP range that you
added.
Note: 选择IP范围添加网络段需注意：
You must not include the gateway (for example,
xxx.xxx.xxx.1), broadcast address (for
example, xxx.xxx.xxx.255), and network
address (for example, xxx.xxx.xxx.0) in the
added IP range.
The network range of a private network cannot
overlap with the public network or management
network on a vRouter offering.
如选择CIDR，需设置以下内容：
CIDR: Enter a CIDR for the
network range, such as 192.168.108.1/24.
Gateway: Set a gateway, such
as 192.168.108.1.
Note:
The first or the last allowed CIDR IP address
can act as a gateway.
If null, the first IP address that is used by
default will serve as a gateway.
DHCP IP: Optional. Set a DHCP
IP address as needed, such as
192.168.108.10.
Note:
If you create an L3 network and enable the
DHCP service for the first time, or if you add the
first network range for the L3 network of the
enabled DHCP service, you can customize the DHCP
IP address.
If the L3 network has a DHCP IP address, you
cannot customize the DHCP IP address when you add
the IP range.
The DHCP IP address can be included or
excluded on the IP range that you added. However,
the DHCP IP address must not be in conflict with
the current CIDR.
If not specified, the system will randomly
specify an IP address within the added IP
range.
The first IP address in a CIDR is deemed as a
gateway by default, and cannot serve as a DHCP IP
address.
Note: 选择CIDR添加网络段需注意：
The IP range specified in the CIDR cannot contain IP
addresses of the link-local address
(169.254.0.0/16).
The network range of a private network cannot
overlap with the public network or management
network on a vRouter offering.
