Just a wild guess if you want to try.

Turn off ICMP redirect:
# echo "0' > /proc/sys/net/ipv4/conf/all/accept_redirects
# echo "0" > /proc/sys/net/ipv4/conf/all/send_redirects

Flush arp cache:
# ip neigh flush all

Flush the route cache:
# ip route flush cache
 
Now try *separate* entries:
# ping -n -c 2 -I source_ip target_ip     
# ping -n -c 2 -I source_if target_ip
