Interesting Routing Problem

["Paul B. Brown" <pbrown btechnet com>]

Gang,

I'm having a problem with activating 2 NICs on one computer.  Both NICs
are on the same Cisco switch.  Here is the info:

eth0 - 38.202.144.145/27
eth1 - 38.202.144.146/27
Gateway: 38.202.144.129

Kernel IP Routing Table:

Destination    Gateway       Genmask          Flags  MSS Window irtt Iface
38.202.144.128 0.0.0.0        255.255.255.224 U     1500 0      0    eth1

IP Forwarding is on

>From 38.202.144.132/27 I can ping 38.202.144.145 without a problem.
However, I can only ping 38.202.144.146 about 50% of the time.  What
gives?  Is this a network config issue on the switch?  How about the
router?  Hummmm . . . how about something in /etc/sysconfig?
