    Hello Community,
    We have an older HP ProCurve 5400zl running K.16.02.0026  that now needs to support OSPF. The provider's requirements for the configuration on their side are quite strict:
    router ospf x vrf xyz
    router-id x.y.z.z
    ispf
    auto-cost reference-bandwidth 10000  ! with 1GE
    capability vrf-lite
    timers throttle spf 100 100 100
    timers throttle lsa 0 10 10
    timers lsa arrival 0
    timers pacing flood 5
    timers pacing retransmission 10
    interface gi x/y/z
    ip ospf dead-interval 3
    ip ospf hello-interval 1
    Special focus is on timer tuning.
    I believe I have already found the correct commands for dead and hello intervals, and since these timers can be adjusted, I assume that establishing an OSPF adjacency should still be possible.
    timers throttle spf 100 100 100 – this is the only one where I found something similar (however, on HPE it's in the seconds range (1–3600), while on Cisco it's in milliseconds).
    Does anyone have a tip for me on how, or if, this can be implemented on this switch?
    Thanks in advance and best regards,
    Sebastian
