Firepower subinterface routing problem

emurray
Level 1
Level 1

I'm new to the firewall world. I have a firepower 1010 using the Fire Power Management Device (6.7.0.1-13) for a home lab. I created two subinterfaces and configure OSPF but one of them is not able to communicate. They both have the same configuration but can't ping from one of them from the router. If I use the connected address I am able to ping, but if I use any other source address from the router I won't. The strange thing is that from the FP I am able to ping. 

 

192.168.50.0/30 VLAN 50 - Ping and works

172.30.90.0/24 VLAN 90 - Does not ping

 

 

What do you guys think could be the issue?

is VLAN 90 in the other side confiuration (where this is connected to switch ?) is the VLAn 90 allowed in trunk ?

On the other side, there is a Router. I attached the picture of the routing table on the router. The subinterface gi 0/0/1.90 has the matching IP. The router can ping from that interface, but as posted on the print screen if I change the source address I can't ping. I have also a layer 3 switch connected to the router and he can't ping either, though the routes appear through OSPF in the switch.

post the configuration on the router side.
