Is there any way to autogenerate MED from IGP? For instance in my case 
I've got:
         if source = RTS_OSPF then {
                 bgp_med = 200;
         }

That works for now with this hardcoded value. However we're going to add 
one more POP with OSPF+BGP and then I want the MED to reflect the 
internal distance to the given subnet.

Like this:
[POP1] --- [POP2] --- [POP3]

The prefix local to POP1 should be announced from all POPs to our BGP 
upstream with the lowest MED from POP1, higher from POP2 and the highest 
MED from POP3. Can I somehow do that automatically?

That's the one, thanks!
