  • 1.  OSPF - Static Routes

    Posted 02-04-2023 20:12

    Hello,
    I have multiple MX204 routers with OSPF areas.
    All the routers are connected to area 0 and each router is connected to different NSSA areas.
    The reason for multiple areas is route summarization.
    I am trying to inject static routes from router A into just area 0 to the rest of the routers.
    I've tried creating an export policy with the `to area 0` condition, but no static routes were exported.
    I would appreciate help in completing this.

    To push a default route into stub ares or nssa just add the default-route parameter to the configuration of the area on the ABR MX.

    Hello,
    I don't need to push a default route.
    I need to push static routes into area 0.

    Sorry for the confusion, on the device where the static routes exist you would create a routing policy and apply this to OSPF.
    set policy-options policy-statement exportstatic1 term exportstatic1 from protocol static
    set policy-options policy-statement exportstatic1 term exportstatic1 then accept
    set protocols ospf export exportstatic1​

    full example and explanation here
