Assuming the 172.18.7.10 self IP is on the same subnet as the 172.18.7.63, you shouldn't need routing to ping between the two IP's.

 

 

I wonder if this might be a problem with the VLAN or trunk configuration between LTM and the switch(es). If there aren't trunks, would you need to use tagged VLANs on LTM? Any thoughts on that angle, Chris?

Aaron - I've never had that as a setup before (tagged port on one side, not tagged on other) but could see that as a problem. If you're configured as a trunk on the F5 but not as a portchannel on the switch, that could most definitely cause issues. I'd start off by changing to an untagged port to see if that changes anything...and if the trunk configs are different, try and standardize it.
