Switching

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.

Hey Jonas_Cheung,

Awesome!! thanks for sharing the good news and for accepting my solution, you are more than welcome mate! Enjoy Junos!
