    Hello Experts,

     

    I have configured two routers in OSPF area 0. But when I check the peer router, it receives OSPF routes with an administrative value of 150 which I learnt as external OSPF. Can anyone please explain why the route is external.

     

     

    root@R2> show configuration protocols ospf
    export New;
    area 0.0.0.0 {
        interface em0.0;
    }
    
    Receiving router:
    
    root@R1> show route protocol ospf
    
    inet.0: 4 destinations, 5 routes (4 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both
    
    2.2.2.3/32         *[OSPF/150] 00:01:53, metric 0, tag 0
                        > to 1.1.1.2 via em0.0
    224.0.0.5/32       *[OSPF/10] 00:36:04, metric 1
                          MultiRecv
    
    root@R1>

    You're redistributing the route in OSPF using export. Expected.

    Hi Folks,

    Just my 2 cents on this…

     

    Please find the default Route Preference Values (Administrative Distance) in JUNOS,
