    Greetings,

     

    I'm trying to configure a very basic ospf between J2350 (Junos-Juniper) and 1841 (IOS-Cisco) cannot form the neigbour relation when i check on cisco it shows init state its a point-to-point connection running JUNOS Software Release [12.1R3.5] can anyone please tell me if junos security blocking any incoming packets coming from the peer (Cisco) looks like cisco recieveing the hello packets and replying back to Juniper  but    Juniper not receiving it. I really appriciate all your help. Thanks in advance

     

    R3#show ip ospf neighbor

    You could additionally run traceoptions while it was in the original state and you would get exactly why it was not forming. But if we could have seen the complete config prior to the change, that would help also.
