16 Patch Release Note
Patch 86251-08 for Software Release 2.5.1
C613-10356-00 REV I
IPv6 tunnelling over IPv4 failed if an IPv4 interface was not configured,
even though an IPv4 interface is not needed for IPv6 tunnelling. This issue
has been resolved.
Multilink Listener Discovery (MLD) packets received on the switch caused
fatal errors. This issue has been resolved.
On the AT-AR020 PRI E1/T1 Port Interface Card (PIC), E bits were not
transmitted in response to received CRC-4 errors. Also, after a period of
Alarm Indication Signal (AIS) reception, Remote Alarm Indication (RAI)
transmission was not terminated. These issues have been resolved.
RIPng received RIP routes from neighbours even when RIPng was disabled.
This issue has been resolved.
A remotely assigned IP address on a PPP interface was not always released
when the connection timed out. This issue has been resolved.
IPSec used with IPv4 sometimes caused a fatal error. This issue has been
resolved.
The SET TIME command caused an error on Refresh timers for IGMP
groups. This issue has been resolved.
The special group entry 01-00-5e-00-00-02 was being written to the layer 2
forwarding database to identify router ports for IGMP snooping. Router
ports are now identified from software, so this special group entry is no
longer written to the layer 2 forwarding database.
An incorrect IPSec Security Association (SA) was used to transmit packets
when the SA’s IP address was assigned dynamically on another VPN
gateway. This issue has been resolved.
DHCP was offering network and broadcast addresses to clients. This issue
has been resolved.
ISAKMP suffered an error when it encountered unknown cryptographic
algorithms. This issue has been resolved.
