I'm using redhat 2.4.9-21 source from 7.2 install & upgrade.

I have rechecked and truly I am not seeing packets go to the
wrong interface.  Our ISP's would drop packets with the wrong
source net.  My IP's are static.  Perhaps that makes a difference?

My experience with tcpdump - in doubt, I don't trust it on the
same machine & verify it on the nexthop.
