[c-nsp] ASR 1002-F BGP table size

I'm having a hard (impossible) time locating performance and BGP specs for
the ASR 1002-F. Since it has a "not really an ESP" built-in, the ESP5/10/20
specs aren't helping me a lot. Other than it should have ~2.5Gbs forwarding
(full-duplex?), I'can't find anything definitive on it. References keep
coming up with the ASR-1002 with the removable ESP.
I'm looking at replacing our upstream routers (7206-VXR/G1) on GigE links
with something that can better handle D/DoS attacks. The original thought
was to use a small 6500/Sup720. Empirical testing shows that Netflow (even
with the table size under control) really beats up on the SP CPU. The
ASR-1002F seems like it should fit the bill, but I found something (that
I've now lost) that mentioned 500K routes.
I'm looking for a device that:
- is a "lightbulb"; relatively inexpensive, single-upstream
- 3 GigE ports
- 1 Gbs full-duplex (2Gbs total) hardware forwarding
- uRPF
- Netflow
- 1,000,000+ IPv4 BGP routes
- IPv6 support
As an additional comment on the Sup720/Netflow, CPU on the SP hit ~30% with
only a couple hundred Mbs and roughly 50% TCAM utilization.
Is the ASR-1002F what I'm looking for? Can anybody direct me to 1002F (vs
modular 1002) specs?
Thanks,
