20Patch Release Note

PCR: 01168

Module: HTTP

Network affecting: No

A watchdog timout occurred when the router received an HTTP message with an over-length header. Normal HTTP requests would also occasionally cause watchdog timeouts. These issues have been resolved.

PCR: 01182

Module: OSPF

Network affecting: No

The OSPF route filter was not filtering out external routes. This issue has been resolved.

PCR: 01193

Module: IPG

Network affecting: No

MD5 Authentication now works correctly with RIP packets.

PCR: 01194

Module: L2TP, IPG

Network affecting: No

The SET IP LOCAL command caused a fatal error if the router was configured with a default route over an L2TP tunnel, because there was no valid route to the remote IP address of the tunnel. This issue has been resolved.

PCR: 01197

Module: Q931

Network affecting: No

Debug messages are no longer generated when a Q.931 Advise of Charge

Notification message is received.

PCR: 01198

Module: TCP

Network affecting: No

TCP sessions would get stuck in the FINWAIT2 state if the remote host did not send a FIN message when required. The router now starts a timer when a TCP session enters the FINWAIT2 state and will automatically close the session if the timer expires.

PCR: 01199

Module: IPG

Network affecting: No

The SET IP FILTER command was not correctly handling the ICMPTYPE and ICMPCODE parameters. This issue has been resolved.

PCR: 01202 Module: DHCP

Network affecting: No

The router will now accept DHCP messages that are greater than or equal to 576 bytes in size, and reject any message smaller than 576 bytes. This operation conforms to RFC 1541.

PCR: 01203

Module: ISAKMP

Network affecting: No

ISAKMP quick mode exchanges are now committed if any traffic is received over the newly generated SA. This improves stability in very lossy networks where the commit message may get lost.

PCR: 01204

Module: ISAKMP

Network affecting: No

ISAKMP debugging caused a fatal error when the debugging mode was set to ALL and PFS was enabled. This issue has been resolved.

PCR: 01205

Module: PPP

Network affecting: No

PPPoE interfaces with IDLE set to ON would not retry active discovery when more data was received if active discovery had previously failed. This issue has been resolved.
