    Hi Folks.

    When viewing routing tables, is S-L-O-W response (several minutes on
    a PII, 225 MHz, 2.4.19 kernel) to the /sbin/route command normal, or
    is it an indication of a misconfiguration? I have two Linux-based
    routers with two Ethernet interfaces, static routing, iptable filtering
    and NATing, etc., and both respond VERY SLOWLY when viewing the routing
    table. /sbin/route responds VERY quickly, however, if a default route
    is either not specified or removed from the routing table. The iptable
    filter doesn't seem to matter (however one machine takes a VERY long
    time (several minutes) to initialize my iptable rules at boot-up).

    Despite this, both machines seem to route and filter packets quite
    nicely. I'm just curious whether the slow response I'm observing
    is normal, or an indication of a problem.

    Thanks in advance...
