so i have junipers, ciscos, and a few <gasp> zebras in an ospf
and ibgp mesh.  they're peering via loopbacks, of course.
unfortunately, i need to recover the space from which the
loopbacks are taken.  of course, i would like to do so with
minimal disruption.  i am thinking of something like the
following:

  o add second loopbacks to all routers with new address in new
    block
  o set up ibgp peerings to new addresses from existing
    peerings
  o change the source of routing updates to new addresses
  o remove old peerings
  o remove old loopbacks

what [else] am i missing?
