Layer 3 Services Configuration

The first step when configuring Layer 3 services on your router is to enable the hardware for those services. If the ASP or Multiservices PIC is used, you must specify the layer of service as either Layer 2 or Layer 3:

lab@sake#set chassis fpc 1 pic 2 adaptive-services service-package ?
Possible completions:
  layer-2              Layer 2 service package
  layer-3              Layer 3 service package

The ASM and J-series routers do not contain this limitation and can support both types of services concurrently. The main building block when configuring JUNOS software services is called a service set, which is a list of service interfaces, service types, and service rules applied to either an interface or a routing next hop. A service set can contain one type of Layer 3 service or a grouping of services such as NAT, IDS, and stateful firewall. If an IPSec VPN is required, you must place it in its own unique service set.
