Setting OSPF interface as Passive

Jump to solution

Is there an AOS command to set a particular interface as an OSPF passive interface, where it doesn't send HELLOs on that interface (good from a security standpoint, especially where there are no downstream routers to form an adjacency with).  However, I need to OSPF advertise these subnets, so the subnet has to be in a OSPF Network statement.

Thank you for asking this question in the support community.  ADTRAN does not have an "OSPF passive-interface" command, currently.  However, if your main goal is to provide OSPF security, then one option would be to enable OSPF authentication on the interface.  In addition to providing security, this would also prevent unwanted OSPF adjacencies from being formed with downstream OSPF routers.

Here is a sample configuration:

interface eth 0/2
   ip ospf authentication message-digest
   ip ospf message-digest-key 1 md5 PASSWORD


Please, do not hesitate to reply to this post with any additional questions or information.  I will be happy to help in any way I can.
