Address Pool Allocation Template Maintenance
Use this screen to maintain address allocation templates. Address allocation templates enable
you to define standard policies that govern the allocation of address space or address pools
within a subnet. For example, you may want to create a template that reserves the first address
within the subnet for a static router assignment, and then all the rest of the space for dynamic
assignment. When you add an “Address Block” (subnet) to a container, you can optionally
assign that block an “Address Pool Allocation Template”. When you do this, address pools
and/or individual IP Addresses will be created within the specific subnet. This capability
allows you to automatically configure subnets using established policies.
