Configuring the Address and Domain for Services Interfaces

On the AS or Multiservices PIC, you configure a source address for system log messages by including the address statement at the [edit interfaces interface-name unit logical-unit-number family inet] hierarchy level:

Assign an IP address to the interface by configuring the address value. The AS or Multiservices PIC generally supports only IP version 4 (IPv4) addresses configured using the family inet statement, but IPsec services support IP version 6 (IPv6) addresses as well, configured using the family inet6 statement.


If you configure the same address on multiple interfaces in the same routing instance, Junos OS uses only the first configuration, the remaining address configurations are ignored and can leave interfaces without an address. Interfaces that do not have an assigned address cannot be used as a donor interface for an unnumbered Ethernet interface.

For example, in the following configuration the address configuration of interface xe-0/0/1.0 is ignored:

For more information on configuring the same address on multiple interfaces, see Configuring the Interface Address.

For information on other addressing properties you can configure that are not specific to service interfaces, see the Junos OS Network Interfaces Library for Routing Devices.

The service-domain statement specifies whether the interface is used within the network or to communicate with remote devices. The software uses this setting to determine which default stateful firewall rules to apply, and to determine the default direction for service rules. To configure the domain, include the service-domain statement at the [edit interfaces interface-name unit logical-unit-number] hierarchy level:

If you are configuring the interface in a next-hop service-set definition, the service-domain setting must match the configuration for the inside-service-interface and outside-service-interface statements; for more information, see Configuring Service Sets to be Applied to Services Interfaces.
