The one they gave you is critical. The fact that you did not use it is
probably an indication of why are are needing help with this. The list
is not the place to give a full IP routing tutorial, but you need to use
the .240, which also a /28 and has 16 address, 14 of which can be used
by devices. The remainder of the 256 block space can be divided and
used however you want.
So, assuming that your are using the first 16 addresses, you could put 8
address somewhere on your network by putting a.b.c.17/29 on a router
port. That becomes the gateway address for devices that connect to that
port. In OSPF you will tell it to redistribute connected routes and you
will put a.b.c.16/29 in the Network section.

If you want the actual subnet the upstream provider gave me was
255.255.255.240 but I put in 255.255.255.0
Which I have block of /13 which only 12 useable ips since the 13^th
one is upstream provider gateway IP.

Routing works by one device knowing the next device to send a packet
to. So the upstream knows that all of you addresses get sent to the
one on your gateway. The provider's devices don't care how the data
gets to the destination, just that it goes to your router. Your OSPF
will tell your headend router how to get the data to the end point.
So, to fully answer your question, you need to answer the one I have
asked you several times. What is the subnet mask our your headend
router connecting to the upstream? Give us that and we can quit
surmising what you might do and give you a how to do it.
Also, from one of your comments, you can tell OSPF whether or not to
propagate your static routers.

Addresses come in pPowers of 2, so you probably have 16 addresses
in the block. So, need to know what subnet mask you use to
connect. If you are using a /29 or /30, the rest can be located
anywhere on the network. Let OSPF do the work. If you are using
the /28 to connect, you will either need to get your provider to
change it or get the rest of the addresses so you can subnet them.
How many addresses do you want at the "remote" site?
Let's say you have a block of 16, a /28. You can have a block of
8, a /29, at the headend and connected to the provider. Then you
can have 8 more somewhere else on the network. As long as you put
the address in OSPF correctly, the 8 addresses from the second
half can be anywhere on your network and OSPF will get them routed
I don’t know if I can even spit up the block like how your saying
because I only have 1 gateway IP address from the upstream
provider unless there is something I don’t know about because one
mikrotik router (core) router is handling the ip’s then from there
its ospf over wireless ptp link to an other mikrotik router with
totally different internal IP address from router a haves.
@ Christian
So if you have a /28 and it was routed to router a, you can route
the whole thing or just subnets to router b, and use them by just
setting a gateway on router b. Or a gateway on router a. Or if it
is ospf you could just assign a single ip to a loopback and do a
1:1 nat to a private. There is a lot of ways to do this, I'm just
not clear on your setup.
This is how I got the network currently setup:
modem ----: routerboard a (w/static wan IP’s w/ospf) then the link
is on ether is going for my ptp to other routerboard b (running
ospf also) on ether1 then I want ether 2-4 run to sectors etc.
So I need to figure out how to route the static wan ip’s over ospf
from routerboard a to b etc..

Scott I got block of 13 and I can go all the way of block of 254 if I
wanted to.
