I created new dhcp pool in server 2012 called vlan 41,routed with default gateway in router, added interface vlan 41 on core switch 3650.
ip address 10.10.41.250 255.255.255.0
ip helper-address 10.10.10.1
i can't ping to this interface from server
Routed 10.10.41.0 255.255.255.0
Other dhcp pools are working fine
