Can I make an assumption that you have a static route in place that states something along the lines of:
set routing-options static route 10.250.x.x/x next-hop 192.168.x.x ????
Then you need to inject that static route into your OSPF network ????
set policy-options policy- statement ospf-static term 1 from protocol static
set policy-options policy-statement ospf-static term 1 ---- Keep going with whatever options you want here
set policy-options policy-statement ospf-static term 1 then accept
set protocols ospf !!!!!! export ospf-static ---- I have not configured this on OSPF so not too sure about area IDs etc hence the !!!!!
This will inject your static routes, taking into account your options in the policy-statement, into OSPF.
Important point to remember is that these statements, when applied, are read in chronological order, so be careful with any added terms with just "accept" in them.
