Default command level
2: System level
Parameters
pool-number: Specifies the address pool number in the range of 0 to 99.
low-ip-address and high-ip-address: Specifies the start and end IP addresses of the address pool. Up to
1024 addresses are allowed for an address pool. If you do not specify the end IP address, there is only
one IP address in the pool, which is the start IP address.
Usage guidelines
You can also configure an address pool for PPP users in system view. An IP address pool configured in
system view is used to assign IP addresses to PPP users who do not need to be authenticated. To specify
the address pool used for assigning an IP address to the peer device, use the remote address command
in interface view.
An IP address pool configured in ISP domain view is used to assign IP addresses to the ISP domain's PPP
users who must be authenticated. Configure IP address pools for ISP domains in scenarios where an
interface serves a great amount of PPP users but the address resources are inadequate. For example, an
Ethernet interface running PPPoE can accommodate up to 4096 users. However, only one address pool
with up to 1024 addresses can be configured on its VT. This is far from what is required. To address the
issue, configure address pools for ISP domains and assign addresses from them to the PPP users by
domain.
Examples
# Configure the IP address pool 0 with the address range of 129.102.0.1 to 129.102.0.10.
<Sysname> system-view
[Sysname] domain test
[Sysname-isp-test] ip pool 0 129.102.0.1 129.102.0.10
