HPE FF 5700-32XGT-8XG-2QSFP+ , ospf hang, can't reset

[slesru]

Hello! I run two HPE FF 5700-32XGT-8XG-2QSFP+ in IRF, they are run quite old software Release 2432P05. Today , without any visible changes in environment, we got problem in routing, which, as we found is in this switches ospf.

Now we have, for instance, down interface:

display interface Vlan-interface 30

Vlan-interface30 Current state:

Administratively DOWN

Line protocol state: DOWN

But it is in routing table:

display ip routing-table | inc Vlan30

192.168.100.0/28 OSPF 10 12 192.168.200.89 Vlan30

192.168.107.0/24 OSPF 10 5 192.168.200.89 Vlan30

192.168.108.0/24 OSPF 10 6 192.168.200.89 Vlan30

and so on

Also I can't do any configuration changes in ospf, or display any info- it just hangs.

What is worse- I can't reset ospf process:

reset ospf process

Reset OSPF process? [Y/N]:y

It hangs forever.

Questions: 1. Can I restart ospf process without rebooting all switches in IRF? 2. Is this known problem and I need just upgrade firmware?

Thank you!

btw, looked in release notes, current release is R2432P06 while we are running 05.

Only fixed problem is:

201801100664/201712070464 •Symptom: Packets cannot be forwarded because the next hop in OSPF routes are mistakenly calculated when OSPF neighbors change.•Condition: This symptom might occur if multiple OSPF neighbors exist in the broadcast domain and the neighbors change.

Yes , we have several neighbours, but there is no info about ospf hang.

Anyway, I'd like to restart ospf without powering off/rebooting both switches in IRF.

Can I do this without service interruption?

Thank you!

Can I try to kill process from display monitor using k? is it possible to send kill -9 to process? Will Comware start process again?

[slesru]

OK, after several tries to kill it ospfd functionality restored. Not good, at all.

Hello 

++ Please find the below procedure to reset the ospf process on comware 

reset ospf process

Use reset ospf process to restart all OSPF processes or a specified process.

Syntax

reset ospf [ process-id ] process [ graceful-restart ]

The reset ospf process command performs the following actions:

• Clears all invalid LSAs without waiting for their timeouts.
• Makes a newly configured Router ID take effect.
• Starts a new round of DR/BDR election.
• Does not remove previous OSPF configurations.

The system prompts you to select whether to reset OSPF process upon execution of this command.

Examples

# Reset all OSPF processes.

<Sysname> reset ospf process

Reset OSPF process? [Y/N]:y

++ Also based on the issue description and as you stated this similar issue is been fixed in R2432P06

201801100664/201712070464

• Symptom: Packets cannot be forwarded because the next hop in OSPF routes are mistakenly

calculated when OSPF neighbors change.

• Condition: This symptom might occur if multiple OSPF neighbors exist in the broadcast domain

and the neighbors change.

I hope this help!!
