Creating an IP Address Range

An IP address range can be reserved for exclusive use for services by defining the

config>router>service-prefix command. When the service is configured, the IP address must be

in the range specified as a service prefix. If no service prefix command is configured, then no

limitation exists.

Addresses in the range of a service prefix can be allocated to a network port unless the exclusive

parameter is used. Then, the address range is exclusively reserved for services.

When defining a range that is a superset of a previously defined service prefix, the subset will be

replaced with the superset definition. For example, if a service prefix exists for 10.10.10.0/24, and

a new service prefix is configured as 10.10.0.0/16, then the old address (10.10.10.0/24) will be

replaced with the new address (10.10.0.0/16).

When defining a range that is a subset of a previously defined service prefix, the subset will

replace the existing superset, providing addresses used by services are not affected; for example, if

a service prefix exists for 10.10.0.0/16, and a new service prefix is configured as 10.10.10.0/24,

then the 10.10.0.0/16 entry will be removed, provided that no services are configured that use

10.10.x.x addresses other than 10.10.10.x.
