MX appliances will now properly validate that DBD packets conform to the appropriate MTU size. If the MX’s OSPF peer has an improper MTU configured, it may cause the OSPF adjacency to fail to properly form. The updated behavior properly conforms to RFC. Please ensure these settings are properly configured on any MX’s OSPF peers to avoid disruption after upgrading to MX 18.1.X.
