What's the netblock and ASN you already have?

Subject: FW: Using BGP to force inbound and outbound routing through 
particular routes

I recently made a request to get a cable modem connection at my home.  
I went for one of those $29.95 for three month specials in case I run 
afoul of some rules prohibiting what I am going to do.  I already have 
a multi-T1 connection with a Class C block and BGP running on my Cisco 
3640 router, and was looking to become multi-homed.  The cable 
connection is via bridge/DHCP cable modem, and was going to hook it up 
to the Cisco 3640.
I have already
done the research and know from what block of IP addresses I will be 
assigned, and the BGP route tables/peers.

I would like to use BGP to force inbound and outbound routing only 
through particular peers, Sprint (AS 1239) and UUNET (AS 701).  I have 
been reading "Practical BGP" by Whate, McPherson and Sangli and this 
appears to be possible.  However, do my adjacent routers need to 
support BGP in order for this to work?  Could I use other routing 
protocols to accomplish this, or would this require knowledge of all 
possible downstream router IP addresses?
