[j-nsp] BGP test method

[chenoi A]

Hai..
 
Currently i hv 20M usage bandwidth on my router and connected bgp with 1 (A)upstream. 
Now i want to have trial with new (B)upstream. from my meetg they could not give me 20M for trial but only can give 6M trial. i request 20M because i want to test my current load with this new provider... how can i test with only 6M with my current load? i now it can be done but how...??
 
have anybody experience this and can it be done with only small capacity of bandwidth and at the same time can test my full load...TQ
