Features in JUNOS Software with Enhanced Services Release 9.3 for J-series Services Routers
JUNOS Software with Enhanced Services Features
Release 9.3R4 of JUNOS software with enhanced services includes the following features. For more information, see the manuals described in List of Technical Publications.
Switching
- IGMP Snooping—Internet Group Management Protocol (IGMP) snooping regulates multicast traffic in a switched network. With IGMP snooping enabled, a LAN switch monitors the IGMP transmissions between a host (a network device) and a multicast router, keeping track of the multicast groups and associated member ports. The switch uses that information to make intelligent multicast-forwarding decisions and forward traffic to the intended destination interfaces. To configure IGMP snooping, use the [edit protocol igmp-snooping] statement. For more information, see the JUNOS Software Interfaces and Routing Configuration Guide.
JUNOS Features Not Supported for Chassis Clusters
For this release of JUNOS software with enhanced services, the following features are not supported when chassis clustering is enabled on the router:
- Packet-based protocols. All packet-based protocols, such as Multiprotocol Label Switching (MPLS), Connectionless Network Service (CLNS), and IP version 6 (IPv6)
- Services interfaces functions. Any function that depends on the configurable J-series services
interfaces:
- ls-0/0/0—Link services Multilink Point-to-Point Protocol (MLPPP), Multilink Frame Relay (MLFR), and Compressed Real-Time Transport Protocol (CRTP)
- gr-0/0/0—Generic routing encapsulation (GRE) and tunneling
- ip-0/0/0—IP-over-IP (IP-IP) encapsulation
- pd-0/0/0, pe/0/0/0, and mt-0/0/0—All multicast protocols
- lt-0/0/0—Real-time performance monitoring (RPM)
- WXC Integrated Services Module (WXC ISM 200)
- Ethernet switching on some PIMs:
- 4-port Fast Ethernet ePIMs running in switching mode
- 8-port and 16-port Gigabit Ethernet uPIMs running in switching mode
- ISDN BRI
