blackhole routes not advertised through OSPF

  • 1.  blackhole routes not advertised through OSPF

    I have x670 and some other switches to do some practice with OSPF.
    I've created simple blackhole routes on switches to check if these routes also be advertised to each other.
    switches have identical routing tables including some other static routes but without those blackholes.
    can someone help me with this topic?

    here are the steps I've followed
    1. created static blackhole
    2. exported to OSPF
    3. check routing table

    Currently EXOS doesn't support exporting blackhole routes into OSPF. You can with BGP, but I'm sure that doesn't help.

    This hub post gives you a workaround.
