How to send out default route ospf when using full bgp?

I can't wrap my head around this. If router one is peered with a full bgp router how do i get the rest of my network to know through ospf that a default route is available since with full bgp there is no default route?

Do I need to use 2 routers at the fiber location? One for the full bgp routes and a 2nd for the ospf to the rest of the network?

If the BGP router with the full view talks OSPF to the other routers, just add "/routing ospf instance set YOURINSTANCE distribute-default
=always-as-type-X" (where YOURINSTANCE is the name of the OSPF instance and X is 1 or 2, depending on how you want to advertise the default route into OSPF).

I got it working ty. Must have been doing something wrong at work. I work in a VERY noisy environment and its hard to concentrate. Logged in from home and got in it going in 2 mins!

If using distribute-always also consider what you want to happen if the upstream fails - especially if there is only one upstream available at that location.
