• I run a network with 22 pfSense servers, and the backbone is a L3 3Com switch. It all runs OSPF and it mostly does so very nicely.

    I've got a problem with one pfSense server.  It has 25 virtual IPs (IF Alias) configured on the WAN interface.  These are each set up as the IP with /26 mask which matches the main interface.

    OSPF is advertising these IF Alias IPs with a /32 mask, and it makes the OSPF routing table much longer than it needs to be.
    I have added both the subnet with /26 and each of the 25 IPs into the Quagga configuration page with "do not distribute" ticked.  It has no affect.  When i save the page, i see the routes disappear from other devices, and then reappear shortly after.

    At another site we have exactly the same, and this one behaves just fine! Weird.

    Any ideas for me to try? Totally stuck!!


  • Forgot to add - ideally i don't want to paste configuration files due to security issues, but i could obscure them.

    I'm running 2.1 release on all nodes.

    "accept filter" seems to work better for excluding such things, unfortunately it gets set on the receiving end not the sending end.

    There must be some difference between the site that works and the one that doesn't, either at the OS level or in the config.

    At the end of the day, though, if it works, it's not really hurting anything to have them show up there.
