Sorry to drag this thread back from the dead, but we're not big enough to merit attention from the Cisco sales boys, so we have to actually put some effort into giving them money.  And the integrators we're dealing with (both for Cisco and Juniper) don't seem to really know which parts go with which…  One gave us a quote for a Juniper MX5 and an ASR-1002 (not X) with no ESP and presented it as if the ASR-1002 could do something without an ESP module installed.

That said, "ASR1002-X essentially tightly packeted ESP40+RP2 into 2U" has me confused.  I'm looking at the first URL noted above (http://www.cisco.com/en/US/prod/collateral/routers/ps9343/data_sheet_c78-450070.html), and while the "integrated" ESP on the 1002-X seems to almost match the ESP-40 for traffic/Mpps, I see that it can only take 1M IPv4 (or? and? split?) IPv6 routes.  For something we want to keep around for many years, that feels a little bit tight.  We currently take two full views.  I would not be surprised if we ended up with 3-4 full views down the road (both IPv4 and IPv6).  

What other limitations might these boxes have when running full bgp views?

What is the relation between the ESP and the number of routes vs. the RP and number of routes?  Datasheets for both ESP and RP have a route limitation.

Also, looking at the RP datasheet (http://www.cisco.com/en/US/prod/collateral/routers/ps9343/data_sheet_c78-441072.html), it's not clear which RP is included when the RP is integrated (everything below the ASR-1004, yes?).  

What does more RAM in the RP buy me?

If I'm reading all these charts right, it looks like the starting point for having more than 1M routes is an ASR-1002 with an ESP-20, correct?

Computers are hard.  Let's go shopping!  Oh wait, shopping is hard… 

Thanks all,

Charles
