CSR1000v is 100% software, so you do not get FIB limitations.

You need the right license to unlock RIB slots, however. We currently
have a Premium license that gives us 500Mbps of throughput + 8GB of RAM.
The 8GB of RAM is fully available for you to use to hold routes.

The RAM also doubles as a place to hold FIB, so again, FIB slots are
limited by RAM, not hardware.

I know the latest IOS XE release for CSR1000v (3.15S, I think) supports
up to 16GB of RAM, and up to 10Gbps of throughput. You can speak to your
SE about the license matrix that gives you the best cost for RAM and
throughput.

1Gbps of traffic through the box should be easy, provided your server
can handle it. CSR1000v, itself, will not be the bottleneck, provided
you have the right license. And I believe there is a 1Gbps throughput
license.
