Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I don't think you can in the drbd.conf (I may be wrong) - I typically 
use bonded interfaces for redundancy, or if the boxes are further away I 
will build OSPF or BGP peering on the environment so you can route 
between both boxes over a couple of different interfaces - Not perfect, 
but it tolerates failures fairly well.
