VRF‑lite OSPF LSAs 3,4,5,7 are not present at Site A CE connected to a PE. Which change resolves the missing LSAs?

The capability vrf-lite command is essential for OSPF to correctly generate Type 3 (summary), Type 4 (ASBR summary), Type 5 (external), and Type 7 (NSSA external) LSAs within a VRF-lite environment. These LSAs are necessary for inter-area and external route propagation. By configuring this command on both the Head Office and Site A routers, which are the customer edge (CE) devices participating in the VRF-lite OSPF process, they will properly originate and receive these LSA types. The PE routers do not require this command as they are typically running MPLS VPN and handle VRF routing differently. The command should be applied under the OSPF process for the specific VRF (e.g., router ospf 1 vrf abc), not globally.
