View This command can be used in the following views:
■ System view
■ ISP Domain view
Description 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.
