You configure the link services interface (ls-0/0/0) on a J-series Services Router to support multilink services and Compressed Real-Time Transport Protocol (CRTP).
The link services interface on a Services Router consists of services provided by the following interfaces on the Juniper M-series and T-series routing platforms: multilink services interface (ml-fpc/pic/port), link services interface (ls-fpc/pic/port), and link services intelligent queuing interface (lsq-fpc/pic/port). Although the multilink services, link services, and link services intelligent queuing (IQ) interfaces on M-series and T-series routing platforms are installed on Physical Interface Cards (PICs), the link services interface on a J-series Services Router is an internal interface only and is not associated with a physical medium or Physical Interface Module (PIM).
For more information about the link services interfaces, see the JUNOS Services Interfaces Configuration Guide.
