The use of sub-interfaces requires q-tags. Assign Q-tags to the sub-interfaces:
configure interface gigabitEthernet 17/1.1 encapsulation dot1q 100
configure interface gigabitEthernet 17/1.2 encapsulation dot1q 101
configure interface gigabitEthernet 18/1.1 encapsulation dot1q 102
configure interface gigabitEthernet 18/1.2 encapsulation dot1q 103

(Optional) Enable RIP on one or more of the VRFs:
configure router rip vrf default enable
configure router rip vrf vrf1 enable
configure router rip vrf vrf2 enable
configure router rip vrf vrf3 enable
configure router rip vrf vrf4 enable
6.
(Optional) Configure the interfaces to which RIP runs:
configure router rip vrf default network 10.0.0.0
configure router rip vrf vrf1 network 20.0.0.0
configure router rip vrf vrf2 network 30.0.0.0
configure router rip vrf vrf3 network 40.0.0.0
configure router rip vrf vrf4 network 50.0.0.0
configure router rip vrf default network 110.0.0.0
configure router rip vrf vrf1 network 120.0.0.0
configure router rip vrf vrf2 network 130.0.0.0
configure router rip vrf vrf3 network 140.0.0.0
configure router rip vrf vrf4 network 150.0.0.0
7.
(Optional) Configure the router ID for the OSPF instances:
configure router ospf vrf default router-id 10.0.0.1
configure router ospf vrf vrf1 router-id 20.0.0.1
configure router ospf vrf vrf2 router-id 30.0.0.1
configure router ospf vrf vrf3 router-id 40.0.0.1
configure router ospf vrf vrf4 router-id 50.0.0.1

Create the OSPF areas:
configure router ospf vrf default network 10.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf vrf1 network 20.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf vrf2 network 30.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf vrf3 network 40.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf vrf4 network 50.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf default network 110.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf vrf1 network 120.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf vrf2 network 130.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf vrf3 network 140.0.0.0 0.0.0.255 area 0.0.0.0
configure router ospf vrf vrf4 network 150.0.0.0 0.0.0.255 area 0.0.0.0
