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.
Refer to the Sun Ethernet Fabric Operating System PIMv6 Administration Guide for more
information about this feature.
ONET Protocol
ONET is an isolated logical grouping of downlink and uplink ports. ONET provides an internal
and external isolated network connectivity for blade servers by bridging downlink ports with
uplink ports that are connected to an external switched network.
In this release, only a one-to-one mapping of a downlink port to an uplink port is supported.
External ports 11 to 14 are unusable.
Refer to the Sun Ethernet Fabric Operating System ONET Administration Guide for more
information about this feature.
PVRST+ Protocol
For an Ethernet network to function properly, only one active path must exist between two
stations. Multiple active paths between stations in a bridged network can cause loops in which
Ethernet frames can endlessly circulate. STP can logically break such loops and prevent looping
traffic from clogging the network. The dynamic control of the topology provides continued
network operation in the presence of redundant or unintended looping paths.
