Well, if you're interconnecting with other large ISPs in 5 places then
you'll get each prefix at least 5 times. Having 5 eBGP sessions between
two ASes is quite common if both are

Hi,
Could anyone give me a sense how many BGP routes a large ISP
typically sees in total?
Here by in total, I mean if the RIB of all routers in the ISP were
merged, how many distinctive
routes would there be?
Thanks,
Yi
I should have said I'm interested in the merged size of RIB-In (which
contains all the raw
routes received).
I couldn't find information about the number of different routes for
the same prefix
a (large) AS typically receives/learns. Hints?

I'd suggest taking a look at the RIBs from routeviews.org or RIPE and
performing an analysis on same. Some
I guess what I see there is the lower bound of the path diversity?
Because even
though an edge router received more than one path for a prefix, it'll
only export
the best route to the other edge routers of the ISP.

Depends on the route server.
