Hi All,
found my problem - it was in R5 - I had left in a network statement from when
I was playing around. Sorry for the trouble. I'm further into the lab now
and I'm
doing redistribution and noticing external confederation routes again - so
it came
to me what might have been wrong. (When I changed routers, I typed in a new
config, thus
my wayward network statement was no longer there.)
