Redistribute BGP and OSPF Routes

Hi, i need help with a problem.

My ISP have an AS and i aready have an Mikrotik Router configured as the BGP Router of the network.
The BGP routes are working just fine. But Now i need to segment my network using OSPF sub routes.

I have configured on the same mikrotik the OSPF network and in the next hop too.

Internaly i can ping from one network to another, but when i try to ping my internal OSPF router from an external network im get stucked in the BGP router.

Can anyone help me?

Thanks

Does your BGP router advertise your network to ISP?

I have checked the option to redistribute the OSPF Routes on the BGP Router.

I have to set this in the OSPF Router too?

Can anyone please help me?

Do your OSPF redistributed networks appear as advertised in bgp advertisments?

No!

I dont know Why. I have setted to redistribute OSPF on the BGP instance

Do you have route filters active?

yes, they set the BGP prepend to simulate an trafic share between my two internet links. But the IP Range anounced in the OSPF route is in the filters.

Can you post your relevant config?
