Known Affected Releases


Description (partial)

Symptoms: After a switch or router boots up, OSPF neighbors continue to flap. 
This situation occurs because, even though the switch or router correctly 
sends and receives OSPF hello packets at every interval, it incorrectly 
detects that the neighbors are down.

Conditions: This symptom is observed on a Cisco Catalyst 6500 series that has 
a Supervisor Engine 32 and that runs Cisco IOS Release 12.2(18)SXF6 and on a 
Cisco 7600 series that has a Supervisor Engine 32 and that runs Release
12.2(18)SXF6 or Release 12.2(33)SRA1.
