Ip Pool Gateway - H3C MSR810 Command Reference Manual

Each address space is represented by a group. One group can contain multiple PPP address pools,
but one PPP address pool can belong to only one group.
One PPP address pool can contain multiple IP address ranges. You can execute this command
multiple times to specify multiple IP address ranges for a PPP address pool. A PPP address pool can
contain a maximum of 65535 IP addresses, and so can an IP address range.
IP address ranges in different groups can be overlapping, but those in the same group cannot.
Changes to a PPP address pool do not affect assigned IP addresses. For example, if you delete a
PPP address pool from which an IP address has been assigned, the IP address can still be used.
When assigning IP address to users through a PPP address pool, make sure the PPP address pool
excludes the gateway IP address of the PPP address pool.
Examples
# Configure PPP address pool aaa that contains IP addresses 129.102.0.1 through 129.102.0.10 for
group a.
<Sysname> system-view
[Sysname] ip pool aaa 129.102.0.1 129.102.0.10 group a

Parameters
pool-name: Specifies an existing PPP address pool by its name, a case-sensitive string of 1 to 31
characters.
ip-address: Specifies a gateway address for the PPP address pool.
vpn-instance vpn-instance-name: Specifies an existing MPLS L3VPN instance by its name, a
case-sensitive string of 1 to 31 characters. If you do not specify this option, the specified gateway
belongs to the public network.
Usage guidelines
The IP pool gateway setting takes precedence over the DHCP pool gateway setting.
An interface on a BRAS must have an IP address before it can assign an IP address from a PPP or
DHCP address pool to a client. This command enables interfaces that have no IP address to use a
gateway address for IPCP negotiation and address allocation.
