IP Gateway

2

Previously, if the IP Helper attempted to redirect packets to an address that

matched the network broadcast address of the egress interface, the packets were

only forwarded if directedbroadcast=yes for the egress interface. By default,

directedbroadcast=no, so such packets were dropped.

This issue has been resolved. IP can now distinguish between packets redirected

by the IP Helper and real directed broadcast packets. If directedbroadcast=no,

IP still redirects packets from IP Helper when necessary.

IPv6

2

For IPv6, if there were multiple equal cost multipath (ECMP) static routes to a

destination, and one or more links for the routes became inactive, the inactive

route was sometimes still chosen for forwarding. This caused brief data delivery

failure to the destination.

This issue has been resolved.

STAR

When the STAR protocol was used for link-layer encryption, the channel setup

failed continuously on heavy traffic.

This issue has been resolved.

IGMP

2

If IGMP snooping was enabled but IGMP was not enabled, the snooper behaved

as if IGMP snooping fast leave had been enabled even when it had not been. This

meant that as soon as the snooper received a Leave message, the port left the

group.

This issue has been resolved. Note that fast leave is disabled by default.

IP Gateway

2

If the router or switch received an IP packet that had been sent as an Ethernet

broadcast, the router or switch responded as if the packet had been sent to its IP

address, even when the packet was destined for a different IP address. In

particular, the router or switch processed and responded to ICMP and TCP

packets that were sent as Ethernet broadcasts to different IP addresses. These

caused the router or switch to send ICMP echo responses or TCP reset packets.

This issue has been resolved. Such Ethernet broadcast packets are generally not

valid packets, so the router or switch now discards them.
