Subnet 162.216.240.0 /23 into smaller subnets for vlan

Management vlan changed to 2 and ip routing enabled.

I am trying to split up a /23 range into /29 subnets on the m6220 switch with each port having a vlan with /29 subnet.

Range: 162.216.240.0/23
Gateway: 162.216.240.1 (upstream provider)

I am trying to figure out what "ip route" commands are needed to route traffic back forth to the subnets. Can someone please assist me in setting up the static route or if this whole approach is invalid.
