u're trying to achieve what is called routing policy.
I know of two way to do this, one is by NAT and the other one is by Policy based routing.
suppose spoke A you have workstation A (wksA) and on the remote site you have 2 servers SvrA and
SvrB. the two site are connected by 2 link Link A and Link B. The policy stated that if wksA wants
to go to SvrA take VSAT link, and the return traffic must be on the VSAT link as well. If wks A
wants to go to svrB use the leased line.
wksa-spoke=======LL========= hub --- svrA
=======VSAT======= --- svrB
What you do is you define a nat on the spoke router such as when wksa access svrA it's nated to a
pool let's say AtoA pool. then you can direct it to reach svrA by the LL by static route. To make
sure the return traffic from svrA to wksA takes the same link, advertised the NAT pool segment
through the VSAT link.
When WksA want's to access svrB, you don't nat it, and since it will flow by normally, it will take
the LL line, and the return traffic from SvrB to wks A can be made to stay on the LL by advertising
wksA segment to the hub router over the LL link.
In short, whenever wksA want's to access SvrA, Nat them and static route them to the VSAT link.
Advertise the NAT pool segment through the VSAT link.
Whenever wksA want's to access SvrB, don't do anything, and since you send the normal segment of
svrB on the LL link, it will take the LL link and return to wksA throught he LL link (you have to
advertise the "real" subnet of wksA on the LL to the hub router).
The other one is Policy based routing, I think it's pretty much straight foward.

Hi Erick,
Thanks for the reply on offset it helps , but i am stuck with one issues
i.e i have servers based in HUB , HUB & Spoke are connected through the
Leased line & VSAT , eigrp is running between them .
Now we want to send the traffic from the server1 & server 2 at HUB through
Leased line to spoke , and the rest of the traffic through VSAT , once the
Leased line down , then the traffic for the server 1 & server 2 at HUB
should move to VSAT .
I tried using offset list offset-list 1 out 20000000 Serial0/0, but the
offset command doesnt take extended access-list so with out it i am not
able to send the just the traffic originating from the server1 & server 2 to
the SPOKE through Leased line , any idea on this
Adarsh
