static route not redistributed into ospf

[naicoram01]

Hello,

We have a problem with the redistribution of static route into the ospf process.

We have the X-core when 4 ospf neighboring and in the configuration of the ospf we have enabled the redistribution of the static route.

when I check the ospf lsdb in another switch I can see the peering up but the static route is not received :

thank you so much for your support.

Hi,

     I had a similar issue with a static route not being distributed to OSPF. I needed to add (enable ospf originate-default cost 1 type ase-type-1)

May not apply to you, but I could not pass traffic out from any of my remote sites until I added that command.

Thanks

Thank you Thomas for your reply.

I had already this command in the configuration (you can see it in the Coeur1-siteX-LTA)... but even with this it doesn't work 😞

[naicoram01]

for info, I can see the route in the FIB in the Coeur1-siteX-LTA :

(vr VR-special) Coeur1-siteX-LTA.14 # debug hal show ipv4fib | i 010.106.000.000
4 010.106.000.000/16 010.150.106.001 4 1000046 00:10:db:ff:60:01 0100000b 3 1 1 F--- 9999

Hi,

maybe it's no OSPF issue.
First I would check whether the route is active in local route table of Coeur1-siteX-LTA:

show iproute vr VR-special

It it is not active, than is will not be redistributed.
