Memory. AIUI, soft-reconfig stores a copy of all the routes before they hit
the route-maps / filters, so you can either examine them (show
received-routes) or re-process them after you change your filters (soft
reload). If you take a full routeing table from your peer, you've suddenly
got to store ~180k routes instead of ~90k routes, which may be an issue,
depending on your router spec.
