    I have ex4200 run ospf nssa, we have new project docking cisco router. I found ex4200 ospf database have nssa route,

    but can't join to route table.

     Hey Jonas_Cheung,

     

    Greetings, these are some common reasons why you could be facing this issue: 

     

    1-Import Policy Is Blocking the Routes

    2-Network Type Mismatch (check the interface type on both sides)

    3-Wrong Address Assignment

    4-If you are using point to point check that both sides are on the same subnet

    5-Check if the forwarding Address Known via an External Route

     

     

    I hope this helps mate! good luck.

    Hey Jonas_Cheung,

     

    As you need to check the configuration on both sides and adjust accordingly, now a couple of things the adv router of this nssa route is: 192.168.11.255 is this how it supposed t be is this supposed to be the RI of the device that is injecting this route? 

     

    Do you have the configuration from 192.168.11.255?

     

    Check all of the kobos that I mentioned before and see if they are synch on both sides.

    Hi Lil,

     

    I found the issue, the problem is ospf network type not consistent.Thank you for your help.

     

    thanks a lot.
