I am trying to test external routed access into the fabric. See attached.
I am running OSPF and the neighbours are formed and I have ACI prefixs on the external switches and the ACI fabric is learning my loopback:
Cisco-3750-01#sho ip route os

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override

I am advertising into the fabric loopback100 (3.3.3.3) from the switch:
Leaf-1# show ip route vrf Test_Lab:CTX1
IP Route Table for VRF "Test_Lab:CTX1"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]

I have a ANY contract between L3EPG and WEB EPG and my VM is in Web EPG. The problem I have is that I can not ping from External(loopback) to VM and from VM to External (loopback).
Should there be an entry in the endpoint cache for my loopback address on the switch?
I don’t have any internal vlan for the L3EPG :
Leaf-1# show vlan
