Will VRF-LITE work for secondary ip address on an interface?

I have the following configuration for an internet router ,where in i have
configured route leaking between VRF internet and global routing table ,
  however the routing is working only for Primary ip address

ip vrf internet
!
interface GigabitEthernet0/0

 ip address 70.1.100.70 255.255.255.252
 ip flow ingress
 ip flow egress

interface GigabitEthernet0/1
