Actually -- I thought that in a partial mesh and no sub-if's, you must
disable it. Or the Hub will not advertise to spoke 1 the routes it learned
from spoke 2 - cuz it is configured on the major interface and thus will not
advertise a network it learned on that interface, out that
interface....wew...Got that? Even with a partial mesh and sub-if's, you
still need it enabled.
If the spokes have a PVC between them, then you are fully meshed and should
disable it IF you are not using sub-if's. If using sub-if's - leave it
enabled. Please correct me if wrong.
