Unhappy OSPF keeps failing


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

Default OSPF neighborship lost after 2 days


As you hav ementioned , you cannot see ospf hellopackets are not being sent , we have to check the status of OSPF on the vlan.

Configure an interface not to be passive. In this mode it does not send hello to its connected neighbors, or process hello from connected neighbors. By default, OSPF interfaces are type BROADCAST (not PASSIVE).

1. Use the show ip ospf interface vlan <vid> command.
2. VerifyType: Passive .
3. Use the ip ospf network broadcast command to type to broadcast.
4. Use the ip ospf enable command to enable OSPF. I believe you have tried it already.

For initial investigation it would be helpful, if you can provide.

1) show ip ospf if stats command.

What's your LSDB size? Is that LSDB and active routes are crossing the limit of routes supported?
Try keeping the interface in passive mode (some of the interfaces).
