A follow up question on this topic..

For Router Loopback Address .... what is wisdom in allocating a /64 vs /128 ?
(the BCOP document suggests this, but does not offer any explanation or merits of one over the other).

I use a /128 -- these addresses are going to be used de-aggregated in
the IGP only; outside they are part of your aggregated allocation. Then
again; I'm using /127 on links. Just because it is a tad easier to do
dual-stack on the scripts that build the config. And, I get to have all
my links in 2001:0db8:f00:feed:dada::/80 :-)
