OmniSwitch 6800/6850/9000—Release 6.1.3.R01 page 67
PR 96061
On an OS6850/OS9000, the IPv6 implementation does not follow ICMPv6 RFC 2463 section 2.2 Message
Source Address Determination in regard to anycast addresses. Instead IPv6 uses any unicast address
configured on the switch.
Workaround: A node that sends an ICMPv6 message has to determine both the source and destination
IPv6 addresses in the IPv6 header before calculating the checksum. If the node has more than one unicast
address, it must choose the source address of the message as follows:
"If the message is a response to a message sent to a multicast or anycast group in which the node is a
member, the source address of the reply must be a unicast address belonging to the interface on which the
multicast or anycast packet was received.

On an OS6850, the SNMP alaIPv6NeighborState MIB object has been deprecated. It is replaced by
alaIPv6NeighborReachability.
Workaround: All SNMP management previously done using the alaIPv6NeighborState object should
switch to the new alaIPv6NeighborReachability object.

A ping6 initiated on an OS9000 to one of its own addresses will succeed, even if the interface on which
the address is configured is disabled or inactive.
Workaround: There is no known workaround at this time.
PR 106826
In certain circumstances, on an OS9000, the RIPng routing table (as shown by the "show ipv6 rip routes"
CLI command) may display an inactive gateway for redistributed routes (i.e. routes redistributed "into"
RIPng).
In the RIPng routing table, the gateway shown is the gateway which was active when the route was origi-
nally redistributed into RIPng. If the original gateway becomes inactive at a time when other active gate-
ways for the route exist, the RIPng routing table will not be updated to display the new gateway. As a
result, the RIPng routing table may display a gateway which is not currently active even though the route
is still active via other gateways.
Workaround: The active gateway for all routes (redistributed and otherwise) is available in the IP route-
manager routing table. Use the show ipv6 router database CLI command to display the IP route-manager
routing table.
