redistributing inter vrf routes in OSPF

[toufik.aibeche@gmail.com]

Hi 

I ma working on a VRF-Lite lab, I craeted 2 VRF instances ( student and staff) 

my network topology has 1 core switch and 2 distribution switches, I am using a cisco 9300 switches with IP routing enabled

i have configured configured OSPF fro my routing protocols for each VRF 

on the core switch I have configured BGP protocols to redistribute inter VRF route (BGP only on the core) to the OSPF instances

i can see all the routes on the core but on the distribution i only see ospf routes from the same VRF

the routes exist in the ospf database but in the table

need help figuring out why the inter VRF routes are no showing or populating in the VRF routing table

Core#show ip route vrf staff
