Configuring Services Interface
An interface service set is used as an action modifier across an entire interface. To
configure the services interface, include the interface-service statement at the
[edit services service-set service-set-name] hierarchy level:
[edit services service-set service-set-name]
interface-service {
service-interface interface-name;
}
Only the interface name is needed, because Junos OS manages logical unit numbers
automatically. The services interface must be an inline-services interface for which you
have configured unit 0 family inet at the [edit interfaces interface-name] hierarchy level.
When you have defined and grouped the service rules by configuring the service-set
definition, you can apply services to one or more interfaces installed on the router. When
you apply the service set to an interface, it automatically ensures that packets are directed
to the Network Address Translation (NAT) engine.
To associate a defined service set with an interface, include the service-set statement
with the input and output statement at the [edit interfaces interface-name unit
logical-unit-number family inet service] hierarchy level:
[edit interfaces interface-name unit logical-unit-number family inet service]
input {
service-set service-set-name <service-filter filter-name>;
}
output {
service-set service-set-name <service-filter filter-name>;
}
You configure the same service set on the input and output sides of the interface. You
can optionally include filters associated with each service set to refine the target and
additionally process the traffic. If you include the service-set statement without a
service-filter definition, Junos OS assumes that the match condition is true and selects
the service set for processing automatically.
NOTE: If you configure service sets with filters, you must configure the service
sets on the input and output sides of the interface.
Configuring Next-Hop Service Sets
A next-hop service set is a route-based method of applying a particular service. Only
packets destined for a specific next hop are serviced by the creation of explicit static
routes. This configuration is useful when services need to be applied to an entire virtual
routing and forwarding (VRF) table, or when routing decisions determine that services
need to be performed.
