Chris,
Thanks for your help. You have solved half of my problem. The other half
problem I have is how to let host A forward packet to router R1 when A needs
send packet to B, and how to let host B to forward packet to router R2 when
B needs send packet to A. Because ISP1 and ISP2 may choose other paths(which
could bypass T1 between R1 and R2) for traffic between A and B.

Subject: RE: Routing Policy
Use Policy Based routing, or Route Maps... Here is a example
let's assume the following is correct.
Host A: 10.1.1.10
Host B: 192.168.16.10
T1
r1 serial: 10.1.2.1
r2 serial: 192.168.15.1
Router 1:
access-list 110 permit ip host 10.1.1.10 host 192.168.16.10
route-map T1 permit 10
match ip address 110
set ip next-hop 192.168.15.1
then you have the oppposite on Router 2:
access-list 110 permit ip host 192.168.16.10 host 10.1.1.10
route-map T1 permit 10
match ip address 110
set ip next-hop 10.1.2.1
This is from memory so don't get made if it is a little off... If I am
understanding you correctly this will do what you want...

Subject: Routing Policy
Hello,
I received a project from the managment team. Please see the diagram. They
want the network traffic between host A and B always cross the T1 line
between R1 and R2.
Host A connects to Internet through ISP1, host B connects to Internet
through ISP2. There is T1 line between router R1 and R2, which is inside the
Internet.
______________________
Host A ---- |--ISP1 R1---T1-- R2 ISP2 --|-- Host B
|________Internet_________|
I have full control of router R1 and R2, host A and B, but have no control
over ISP1 and ISP2. I am not sure what is the best way to setup this kind
routing policy. Anybody has any experience/ideas, please shed some lights
here. Thanks!
Roger Lu
