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?
