Re: weird problem with ping (I know, shame on me)

Hi Larry,
I can ping successfully from the 6509 using the source IP of the vlan on
which the user sits. From the user's PC, cannnot ping the same address! If I
do a trace from the pc, it does after 8 hops. I don't know what the 8th hop
is, as I'm not able to telnet to it (connection refused). When I get into
the 7th hop and do a trace for the destination IP, the route points to a
different machine than the 8th hop in the traceroute. That is weird.
