Features in 86253-07

Patch 86253-06 was not released.

Patch 86253-07 includes all issues resolved and enhancements released in previous patches for Software Release 2.5.3, and the following enhancements:

PCR: 03941

Module: FIREWALL

Level: 2

TCP Keepalive packets for FTP sessions were passing through the firewall during the TCP setup stage with TCP Setup Proxy enabled. Keepalive packets include sequence numbers that have already been acknowledged. Such packets now fail stateful inspections and are dropped by the FTP application-level gateway.

PCR: 03961

Module: PIM, PIM6

Level: 2

The PIM-DM prune expiry time was not reset when a State Refresh message was received. This issue has been resolved.

PCR: 03997

Module: IPG

Level: 3

When policy-based routing was active, IP packets not matching any policy- specific routes were forwarded, even if there was no default policy route. This issue has been resolved. Now, a route whose policy exactly matches the policy of the packet is selected. If an exact match does not exist, a route with the default policy will be used to route the packet. If no route is found, the packet is discarded. The TOS field in incoming IP packets is ignored, so packets with the TOS value set are forwarded using a route with the default policy.

PCR: 31080

Module: IPv6

Level: 2

When a ping was sent to the device’s link-local address, the device flooded the ICMP Reply packet over the VLAN. This issue has been resolved.

PCR: 31104

Module: OSPF

Level: 2

Occasionally when a device rebooted its OSPF routes were missing from the route table. This issue has been resolved.
