Patch Release Note
Patch 86222-27 for Software Release 2.2.2
C613-10319-00 REV Z
TCP has been excluded from this enhancement because TCP has the MSS
(Maximum Segment Size) parameter for segment size control. Also, for
PPPoE interfaces with a reduced MTU of 1492, a previous enhancement in
PCR 02097 ensures that TCP MSS values in sessions carried by a PPPoE
interface are clamped to a value that prevents fragmentation.
When pinging to a remote IP address with two or more different cost routes,
if the preferred route became unavailable, the ping failed to switch to the
less preferred route until the ping was stopped and restarted. This issue has
been resolved.
When the system time was set to a time that was before or significantly after
the current time, Firewall sessions were prematurely deleted. This issue has
been resolved.
When the router priority was changed on a dynamic OSPF interface, the
new priority did not appear in the output of the SHOW OSPF NEIGHBOUR
command on neighbouring routers. The new priority only showed after the
RESET OSPF command was executed on the neighbouring routers. This
issue has been resolved.
After setting the IGMP query timer with the SET IP IGMP command, and
saving the configuration, the IGMP Other Querier timeout was not set to the
correct value after a restart. This issue has been resolved.
Entries in the process of being reclaimed as static entries (and waiting for
the remote IP to become routable), were disrupting the reclaim process. This
prevented further entries from being reclaimed. DHCP static entries are
now fully subject to normal reclaim processing.
If the ENABLE IP IGMP command was executed before the ENABLE
SWITCH L3FILTER command, Layer 3 filtering did not discard packets
destined for the CPU. This issue has been resolved.
Link state advertisements could incorrectly show an area as a stub area. This
happened during the time when a Direct Route (DR) was removed from a
configuration and before a Direct Backup Route (BDR), or an Other Direct
Route (Other DR) was elected. This issue has been resolved.
Sometimes IP flows were not deleted correctly when both directions of the
flow were in use. This issue has been resolved.
When the TX cable was unplugged from a fibre port the operating status
was incorrectly reported as
UP
. This issue has been resolved.
