High ping latency using two ethernet under FreeBSD 4.11 ...

Testing my network, I just noticed the following:
--- 200.46.204.1 ping statistics ---
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max/stddev = 399.664/407.119/420.315/8.267 ms
--- 200.46.208.1 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/stddev = 373.045/409.266/453.402/33.280 ms
400ms to my default router seems a wee bit high ...
I'm suspecting that it has to do with:
Mar 15 01:13:28 neptune last message repeated 10 times
Mar 15 01:13:28 neptune /kernel: arp: 200.46.204.1 is on em0 but got reply from 00:0b:bf:42:a8:06 on em1
Mar 15 01:13:28 neptune /kernel: arp: 200.46.208.1 is on em1 but got reply from 00:0b:bf:42:a8:06 on em0
In order to provide network redundancy, and simplify our scripting, with
have one network bound to one ethernet port, and the other network bound
to the second one on the same machine ...
I'm plugging everything into a Cisco 2924 ... is there some way, either on
the FreeBSD side, or Cisco, of 'cleaning this up'?
