Software Supported

Multicast boundaries confine scoped multicast addresses to a particular domain. Confining scoped addresses helps to ensure that multicast traffic passed within a multicast domain does not conflict with multicast users outside the domain.

PIM

PIM-SSM

Protocol-Independent Multicast (PIM) is an IP multicast routing protocol that uses routing information provided by unicast routing protocols, such as RIP and OSPF. PIM is “protocol-independent” because it does not rely on any particular unicast routing protocol. Sparse mode PIM (PIM-SM) contrasts with flood-and-prune dense mode multicast protocols, such as DVMRP and PIM Dense Mode (PIM-DM) in that multicast forwarding in PIM-SM is initiated only via specific requests, referred to as Join messages.

PIM-DM for IPv4 is now supported with the 6.1.3.R01 release. PIM-DM packets are transmitted on the same socket as PIM-SM packets, as both use the same protocol and message format. Unlike PIM-SM, in PIM-DM there are no periodic joins transmitted; only explicitly triggered prunes and grafts. In addition, there is no Rendezvous Point (RP) in PIM-DM.

Protocol Independent Multicast Source-Specific Multicast (PIM-SSM) is a highly-efficient extension of PIM. SSM, using an explicit channel subscription model, allows receivers to receive multicast traffic directly from the source; an RP tree model is not used. In other words, a Shortest Path Tree (SPT) between the receiver and the source is created without the use of a Rendezvous Point (RP).

Multinetting

This feature allows IP traffic from multiple subnets to coexist on the same VLAN. A network is said to be multinetted when multiple IP subnets are brought together within a single broadcast domain (VLAN). It is possible to assign up to eight different IP interfaces per VLAN.

NTP Client

The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver. It provides client time accura- cies within half a second on LANs and WANs relative to a primary server synchronized to Universal Coordinated Time (UTC) (via a Global Positioning Service receiver, for example).

OSPFv2/OSPFv3

Open Shortest Path First version 3 (OSPFv3) is now available with the 6.1.3.R01 release on the OmniSwitch 6850 Series and OmniSwitch 9000 Series. OSPFv3 is an extension of OSPF version 2 (OSPFv2) that provides support for networks using the IPv6 protocol. OSPFv2 is for IPv4 networks.

Both versions of OSPF are shortest path first (SPF), or link-state, protocols for IP networks. Also consid- ered interior gateway protocols (IGP), both versions distribute routing information between routers in a single Autonomous System (AS). OSPF chooses the least-cost path as the best path. OSPF is suitable for complex networks with a large number of routers by providing faster convergence, loop free routing, and equal-cost multi-path routing where packets to a single destination can be sent to more than one interface simultaneously.

The following features are also supported by both versions of OSPF:

•Graceful (Hitless) Support During Failover, which is the time period between the restart and the rees- tablishment of adjacencies after a planned (e.g., the users performs the takeover) or unplanned (e.g., the primary management module unexpectedly fails) failover.

•OSPF adjacencies over non broadcast links.
