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

    Posted May 09, 2019 01:11 PM

    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?

    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!!
