Address pool is used in priority order for assigning IP addresses to mobile stations which have not requested
a specific address pool.
a specific address pool.
priority
must be an integer from 0 through 10 with 0 being the highest priority.
The default value is 0.
static
Designates local IP address pool to statically assign pooled addresses.
Important:
The keyword static must be used for DHCP served IP addresses.
tag { none | pdif-setup-addr }
Default:
none
none
: default tag for all IP address pools
pdif-setup-addr
:pool with this tag should only be used for PDIF calls.
address-hold-timer seconds
When this is enabled, and an active subscriber is disconnected, the IP address is held or considered still in
use, and is not returned to the free state until the address-hold-timer expires. This enables subscribers who
reconnect within the length of time specified (in seconds) to obtain the same IP address from the IP pool.

reconnect within the length of time specified (in seconds) to obtain the same IP address from the IP pool.
seconds
is the time in seconds and must be an integer from 0 through 31556926.
Important:
Currently, the address-hold-timer only supports IPv4 addresses.
address-quarantine-timer
seconds
Specifies the timer value in seconds for an address quarantine timer as an integer from 20 through 86400.
This timer cannot be configured with an address-hold-timer in the same pool.
The IP pool address-quarantine-timer is a mechanism to busy out a released IP address for a specified
interval. This prevents an IP address from being reused until the quarantine timer expires.
Each IP pool can be configured with a timer value that determines how long a recently released address will
be held in quarantine before being freed. When the timer has expired, the address is returned to the list of free
addresses, to be allocated again to a new subscriber. Any address that has been released, but for which the
address-quarantine-timer has not expired, is still considered to be in use for the purposes of allocation. If a
subscriber tries to reconnect while the address-quarantine timer is armed, even though it is the same
subscriber ID, the subscriber does not get the same address.

advertise-if-used
Advertises to the peer routes only if addresses are being used in pool.
alert-threshold { group-available | pool-free | pool-hold | pool-release | pool-

used } low_thresh [ clear high_thresh ]
Default: All thresholds are disabled.
Configures IP address pool-level utilization thresholds. These thresholds take precedence over context-level
IP pool thresholds.

group-available
: Set an alert based on the available percentage of IP addresses for the entire IP pool
group.
pool-free
: Set an alert based on the percentage of IP addresses that are unassigned in this IP pool.
