[c-nsp] c3560 L3 throughput with BGP

[Jan Hrabcak]

Hello,

i'm using cisco 3750g with 40 bgp peers, cca 3000 prefixes with about 
300mbit/s in peaks. Load is constantly during whole day on 6% with sdm 
routing template. c3750g is the same as c3560g without stacking I think.

Best regards,
Jan Hrabcak
