The local address server allocates IP addresses from a pool of addresses stored locally on the router. You can optionally configure shared local address pools to obtain addresses from a DHCP local address pool that is in the same virtual router. Addresses are provided automatically to client sessions requiring an IP address from a virtual router that is configured to use a local address pool.
A local address server is defined in the context of a virtual router. You create a local address server when you configure the first local pool. Local address servers exist as long as the virtual router exists or until you remove them by deleting all configured pools.
Figure 1 illustrates the local address pool hierarchy. Multiple local address server instances, one per virtual router. can exist. Each local address server can have one or more local address pools. Each pool can contain a number of IP addresses that are available for allocation and used by clients, such as PPP sessions.
