[nsp] regexp question

[David Curran]

You might want to check and see if your local IX sets any communities on
their direct customers.  If so, you could use those communities to set local
pref.  I know most of the major providers do that.  Not sure who yours is
but its worth a look

Hi
My case is a bit special(maybe..). We are a lab at a university and our
upstream(the university) gives us a default route which they get by the
national university network. We are also connected to a local IX on which we
peer with smaller/medium sized service providers. Some of these are conneced
to larger IX:es. The "problem" is that I know that some of the networks we
get through our peers on the local IX can be reached in a better way through
our upstream(2-4 hops) and not through the local IX. I would like to avoid
getting the upstream to give us a full routing table.
