Good stuff. I changed the OSPF cost at both ends like suggested, and the path re-routed. I did not have to do anything to the LDP (Running RouterOS v6.32.4). Huge help.
Is there any way to change costs on dynamic OSPF interfaces, or do they always need to be fully manually configured to change cost?
