[j-nsp] Problem exporting BGP routes.

make sure that you have a full mesh at the physical layer

Hi Stephen,

Are the routes you try to export to your iBGP peers, also learned
from iBGP peers?

Because prefixes received from iBGP speakers are only advertised
to eBGP speakers.

If this is what you want you can consider a fully meshed network, use
route-reflectors or confederations.

Gr, Richard
