Multicast Listener Discovery
Multicast listener discovery (MLD) works with IPv6 to control the reception of multicast data in a network. MLD functions similarly to IGMP, which manages multicast groups for IPv4. The MLD snooping (MLDS) function supported in this release enables switches to forward multicast data to only hosts that need to receive the data, rather than to all ports. MLDS enables a switch to snoop or capture information from MLD packets that are being sent back and forth between hosts and a router. Based on this information, the switch adds or deletes the multicast addresses from its address table, thereby enabling or disabling multicast traffic that is flowing to individual host ports.
Refer to the Sun Ethernet Fabric Operating System MLDS Administration Guide for more information about this feature.
Open Shortest Path First version 3
Open Shortest Path First version 3 (OSPFv3) adds support for IPv6 in the OSPF protocol. As described in RFC 2740, the fundamental mechanisms of OSPF (flooding, DR election, area support, and SPF calculations) remain unchanged in OSPFv3. However, some changes to OSPF were made to handle changes in protocol semantics between IPv4 and IPv6 and increased IPv6 address sizes.
Refer to the Sun Ethernet Fabric Operating System OSPFv3 Administration Guide for more information about this feature.
Routing Information Protocol Next Generation
Routing Information Protocol next generation (RIPng), supported in this release, adds support for IPv6. RIPng functions similarly to RIP in IPv4 and offers the same dynamic route learning benefits. RIPng enhancements for IPv6, as detailed in RFC 2080, include support for IPv6 addresses and prefixes and the use of an all-RIP-routers multicast group address as the destination address for RIPng update messages. The IPv6 RIPng local routing table (RIB) contains a set of IPv6 RIP routes learned from all its neighboring networking devices.
Refer to the Sun Ethernet Fabric Operating System RIPng Administration Guide for more information about this feature.
Protocol Independent Multicast v6
Protocol Independent Multicast v6 (PIMv6) adds support for IPv6 in the PIM routing protocol. PIM is designed to provide scalable inter-domain multicast routing across the internet. PIM is a collection of multicast routing protocols, each optimized for a different environment. PIM provides multicast routing and forwarding capability to a router that runs IP along with Internet Group Management Protocol (IGMP). PIM depends on IGMP for multicast group membership information. PIM routes the multicast data packets independent of any unicast routing protocol.
Release 1.2 provides support for PIMv6 Sparse Mode.
