RIPE's RIS and Route-View's both archive BGP tables and you can download
them and manipulate them. There are several other services that archive
the data, like Renesys, but don't provide raw data downloads.
SNMP is really a non-starter for this work. Too slow, the table changes
out from under you, plus it's hugely inefficient.
