3850 inter-vlan routing

I have a stack of 3 3850's and am trying to route between Vlan 100 and 200. Both VLANs have an IP address configured, IP routing is on.

From VLAN 200 GI1/0/11 (PC ip address GW I can ping and (VLAN 200 and 100 IP addresses).

From VLAN 100 GI2/0/5 (PC IP address GW I can ping and 100.250, but not here is the "sho IP route"

Production-Stack#sh ip rout
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
       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

Gateway of last resort is to network

S* [1/0] via is variably subnetted, 2 subnets, 2 masks
C is directly connected, Vlan100
L is directly connected, Vlan100 is variably subnetted, 2 subnets, 2 masks
C is directly connected, Vlan200
L is directly connected, Vlan200
