Core routers normally have the full routing table. A router in the access
layer should only have 2 paths to the distribution layer. It depends what
you're doing. We try to aggregate routes at the distribution layer.
eg. when you're dialing into an ISP, you want one path to the core and be
able to reach everything from there (internet, server,...)
The size of a routing table depends on how big you're network is. For a NAP
or a core router running BGP, you'll find about 59'000 network entries and
120'000 paths (internet routing table).

Subject: Re: How Many Routing Tables
Just as a follow-up question: Can somebody tell me how many route entries
there
are in edge and core routers nowadays?
Thanks,
