I was wondering if global IPv4 Routing can be technically achieved only by importing from the ISP Provider (providing us with a IPv4 BGP full table) a subset from the BGPv4 routes (i.e. all prefixes up to /22), and without configuring any additional static default route towards the Provider.
Reason behind my question: we have an equipment which is only capable to import (due to licensing) a maximum amount of BGP routes and we would like to know if, from the routing point of view, this concept might be feasible.
Thanks.
