OSPF Failing Avaya 4500 series Switches

[ToxicMyst]

Hi

we have ERS 4500 series switches in 2 stacks with advanced licensing enabled.
Both stacks are running the following HW:03 FW:5.3.0.3 SW:v5.6.1.053

We enabled OSPF on the stacks and it ran fine for 2 days before stopping.

We have rebooted the stacks enabled and disabled ospf but we have been unable to get it to run for more than a few hours before it dies again.

Anyone suggest any reason why this may be happening and or what we may do to fix the issue.

A trace reveals that the stacks nolonger send out OSPF Hellos.

Cheers

R.

I found this in the 5.6.2 release notes

wi01049818 - OSPF: Missing Hellos: The switch will now correctly send OSPF Hello Packets on reception of requests from an OSPF peer. Previously in some situations the switch would send out requests only every 10 seconds or longer which could result in loss of OSPF adjacency.

It may be worth upgrading your software.
