When a group of pools have the same priority, an algorithm is used to determine a probability for each pool
based on the number of available addresses, then a pool is chosen based on the probability. This method, over
time, allocates addresses evenly from the group of pools.
based on the number of available addresses, then a pool is chosen based on the probability. This method, over
time, allocates addresses evenly from the group of pools.
Important:
Note that setting different priorities on each individual pool in a group can cause addresses in some
pools to be used more frequently.
Important:
In NAT IP pool configurations, the minimum number of public IP addresses that must be allocated to
each NAT pool must be greater than or equal to the number of Session Managers (SessMgrs) available on the system.
On the ASR 5000, it is >= 84 public IP addresses. This can be met by a range of 84 host addresses from a single Class
C. The remaining space from the Class C can be used for other allocations.

Example
The following commands define a private IP address pool, a public IP address pool, and a static address pool,
respectively.
The following commands define a private IP address pool, a public IP address pool, and a static address pool,
respectively.
The following command defines a private IP pool specified with a range of IP addresses. The pool has 101 addresses.
The following command sets the address hold timer on the pool to
minutes (
seconds):
The following command removes the IP address pool from the configuration:
The following command creates a static IP pool:
The following command resizes the static IP pool created in the previous example:
