Probably not the safest way to go about it. Might work out ok, but
with the dramatic potential to blow something up, especially on a router
with a full table. The bgp mib doesn't contain an object to tell you,
summarized, how many prefixes a peer is sending. You would have to iterate
the full routing table and pick out routes that originate from a specific
AS. And then repeat it periodically to generate your time series.
You'd be better off parsing output from a zebra peer. Slightly hackish but
far safer, and efficient.
