OSPF Hardening for Cisco FIREPOWER Global OSPF and Cisco Switch VRF OSPF

Hi all,

As I have firewall and L3 switches connected in an infrastructure.
Cisco FirePOWER is configured with Global OSPF as VRF is not supported.
Cisco Switch is configured both Global and VRF OSPF.
Before the following hardening is performed, the routing is working (as in I am able to see all the routes by using 'show ip route vrf 1' on switch and 'show route' on the firewall.

However, after the hardening is performed. The route breaks. (not able to see all the OSPF routes)

I have performed the following OSPF hardening on both firewall and switch.
- OSPF Authentication Message Digest
- ip ospf message-digest-key {ospf_md5_key-id} md5 {ospf_md5_key}

I have ensured that the firewall and switch use the same OSPF key-id and MD5 key, but stilll does not work.

Please advise
Thank You
Peter
