OSPF Route Types in RT

  • 1.  OSPF Route Types in RT

    Posted 01-18-2021 00:27
    Hi
    In Cisco IOS we can find out the OSPF route-type  by checking the  routing table. for example LSA Type#3 is marked with O IA or NSSA type 2 is noted by N2. In JunOS by checking routing table this information is not shown. How can we find out the route-type by checking the routing table?
    for example in Following output how can we say which routes are Intra-Area(O) which ones are Inter-area(O IA) and so on...(I know I have both External routes and NSSA routes but  there is no distinction between them in RT)

    jcluser@vMX1> show route protocol ospf

    inet.0: 21 destinations, 22 routes (21 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    "show ospf route" might be what you're looking for.

    You can specifically view inter and intra as well.

    "show ospf route inter"
    "show ospf route intra"
