I am running an OSPF network (see image)
Everything is running very good and the redundancy works good sa well.
I would like to get full duplex from Router A right through to Router F, or from any Router to any router.
I have tried the wiki’s, but most wiki’s are only from A to B and not from A to B to C to D.
Any suggestions with how to use coting on this layout or any other suggestions

Any given router has to have at least two interfaces which connect to its neighbor. Edit one of the interfaces on one of the routers and set its cost to a number other then the default 10… like 9. The router will prefer the interface with the lowest cost when transmitting to its neighbor. On the neighbor set the opposite interface’s cost to the chosen number (ie 9). This causes traffic going one direction to all go over the same link… two half duplex links used in only one direction is a full duplex link.
You would have to do this on each router’s connection to each neighbor.
I would recommend naming your interfaces something to help you remember the config for example you may rename router A’s interfaces like:
ether0-TX-toRtrB
ether1-RX-fromRtrB
