Creating Local IP Address Pools

IP address pools are configured for virtual routers. To make the E-series router use the address pools specified on the virtual router, the virtual router must have the addressing scheme set to Local.

You can configure the E-series device to provide an IP address during the authentication process. These IP addresses must be configured in a local IP address pool. Each address pool must be associated with a virtual router before it can be used.

Each local address pool is named and contains ranges of sequentially ordered IP addresses. These addresses are allocated when the AAA server makes a request for an IP address.

If a local address pool range is exhausted, the next range of addresses is used. If all pool ranges are exhausted, a new range can be configured to extend or supplement the existing range of addresses, or a new pool can be created. The newly created pool range is then used for future address allocation. If addresses allocated from the first pool range are released, then subsequent requests for addresses are taken from the first pool range.

To create a local IP address pool:

1. From the Device-wide Explorer, select Virtual Routers, right-click, and click List All.

A listing of all available virtual routers appears in the list area.

2. Select a virtual router in the list, right-click, select Create, and click Local IP Address Pools.

The Create Local IP Address Pool dialog box appears.

3. Set the local IP address pool parameters (Table 38).

 Table 38:  Local IP Address Pool Parameters 

 Parameter

Configuring and Viewing IP Address Pools

You can add and remove IP address ranges for existing IP address pools by listing all address pools associated with a virtual router, right-clicking, and then clicking Configure. The Local IP Address Pool tab appears in the work area, with the Add and Remove parameters available.

You can also view the number of addresses per range, the number in use per range, and the percentage of address utilization by listing all address pools, right-clicking, and then clicking View. The results are displayed in the work area on the Local IP Address Pool tab.
