Hi,   I am trying to set up an OSPF adjacency between a Meraki MS250 and a Cisco firepower. All settings are fine. My problem is that the adj is not forming. It goes from init to exstart to exchange and then again init and it continues. According to the OSPF debugs from the firewall, hellos are exchanged, firewayy is sending DBD but not receiving, retransmitting but receiving any reply so it goes in circules.   We are very limited because Meraki has not so many option for OSPF. Can you please help me what could be the problem?   Thanks, Gergely ... View more
