Do you see the request hit the endpoint in question?

Do you have the routes in your non-default RD? That was not explicitly called out.  You just said there were routes there.

If you tcpdump on the bigip with -nei 0.0, are you seeing the requests hit the appropriate route domains and exiting towards the ACI?

I've shared ip route in respoonse to buulam's reply and query. Can you kindly have a look. I didn't get a chance to do the tcpdump with -nei. Will trying following will provide desired output considering client can only ping: 

 tcpdump -nni 0.0:nnnp -s 0 host

 

Can you please correct me if it's wrong. Thanks!
