Overriding Default DHCP Local Server Configuration Settings
Subscriber management enables you to override certain default DHCP local server
configuration settings. You can override settings at the global level or in a routing instance
level, for a named group of interfaces, or for a specific interface within a named group.
•
To override global default DHCP local server configuration options, include the overrides
statement and its subordinate statements at the [edit system services dhcp-local-server]
hierarchy level. In a routing instance, include the overrides statement and its subordinate
statements at the [edit routing-instances routing-instance-name system services
dhcp-local-server] hierarchy level.
•
To override DHCP local server configuration options for a named group of interfaces,
include the statements at the [edit system services dhcp-local-server group group-name]
hierarchy level. In a routing instance, include the statements at the [edit
routing-instances <routing-instance-name> system services dhcp-local-server group
group-name] hierarchy level.
•
To override DHCP local server configuration options for a specific interface within a
named group of interfaces, include the statements at the [edit system services
dhcp-local-server group group-name interface] hierarchy level. In a routing instance,
include the statements at the [edit routing-instances routing-instance-name system
services dhcp-local-server group group-name interface] hierarchy level.
To override default DHCP local server configuration settings:
1. Specify that you want to configure override options.
Global override:
[edit system services dhcp-local-server]
user@host# edit overrides
Group level override:
[edit system services dhcp-local-server]
user@host# edit group boston overrides
Per-interface override:
