SDA fabric edge issue

Dears,
I have an SDA fabric with two switches one act as BCE border,control and edge, the other switch act as Edge only.
Everything looks fine according to the BCE, when i connect any user on the BCE switch, the user sees all the routes inside and outside the fabric.
But the edge switch routing table doesn't have all the routes only the connected users. and the end user can't ping anything except the gateway.

the end user IP is 172.16.1.22

i can ping it from Edge switch
but I can't ping it from the BCE switch.

the BCE switch

SDA-BCE-SW#show ip route vrf VN1

Routing Table: VN1
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, m - OMP
n - NAT, Ni - NAT inside, No - NAT outside, Nd - NAT DIA
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
H - NHRP, G - NHRP registered, g - NHRP registration summary
o - ODR, P - periodic downloaded static route, l - LISP
a - application route
+ - replicated route, % - next hop override, p - overrides from PfR
