undo ip pool pool-number
View
System view, ISP domain view
Parameter
pool-number: Address pool number, ranging from 0 to 99.
low-ip-address and high-ip-address: The start and end IP addresses of the address
pool. The number of in-between addresses cannot exceed 1024. If end IP address
is not specified, there will be only one IP address in the pool, namely the start IP
address.
Description
Use the ip pool command to configure a local address pool for assigning
addresses to PPP users.
Use the undo ip pool command to delete the specified local address pool.
By default, no local IP address pool is configured.
You can configure an IP address pool in system view and use the remote address
command in interface view to assign IP addresses from the pool to PPP users.
You can also configure an IP address pool in ISP domain view for assigning IP
addresses to PPP users in the current ISP domain. This applies to the case where an
interface serves a great amount of PPP users but with inadequate address
resources for allocation. For example, an Ethernet interface running PPPoE can
accommodate 4095 users at most. However, only one address pool with up to
1024 addresses can be configured on its Virtual Template (VT). This is obviously far
from what is required. To address the issue, you can configure address pools for
ISP domains and assign addresses from them to their PPP users.
Related command: remote address.
Example
# Configure the local IP address pool 0 with the address range of 129.102.0.1 to
129.102.0.10.
[SecBlade_FW] domain 3com163.net
[SecBlade_FW-isp-3com163.net] ip pool 0 129.102.0.1 129.102.0.10
