Hello Mostafa !

   First, thanks for your answer!

   Second, as you said,  i will use BGP only between ISP1 (ISP2) and 
3660 and other protocol (iGRP or RIP) between 3660 and 7200 ?

   How BGP in 3660 will load balacing requests from my network without 
being equal? I mean if i'm using 1.3 mb from ISP1 and 512k from ISP2 and 
my delay time to access X (in the internet) is 0.7 ms in ISP1 and 0.3 ms 
in ISP2, how BGP will choose the best option?

      Thanks again !!!

         Marcelo

Detail: Joshua said to me to throw away my 3com router and just use 3660 
to receive both ISPs. By the way, thanks to you Josh too!
