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

[Mounir Mohamed Ali]

Hi Rick,

Here is a quick comparison.

The Cisco ASR 1002-F has RP1 with 1G RAM, ESP 2.5 with 1G RAM (2.5Gbps
bandwidth), SIP-10, 1SPA, and 4 GE ports  built in chassis, running IOS-XE
and has SW redundancy via VM, capcable to have 500K IPv4 and 125K Ipv6

The Cisco ASR1002 has 1 RP1 integrated in the chassis comes with 4GB RAM by
default, 1 ESP slot for ESP5/10 to provide 5Gbps/10Gbps bandwidth, it also
has 4-built in GE-ports, 3 SPA ports, running IOS XE and has SW redundancy
via VM.
