John, I appreciate your opinion, however I would like to keep the responses to my question on a pure technical level. I can assure you that there will be full disclosure if this solution is implemented. Thanks for your response :-) --Jeff --- John Fraizer <nanog@Overkill.EnterZone.Net> wrote:
I would be very upset if I were "Company X" and I found out that you were policy-routing my traffic to the "cheap" connection vs the best connection.
Is it just me or do others on the list believe that in the absence of full disclosure this would be shady at best?

Hello,
I am a network engineer at a regional southeast
NSP. I am looking for some recommendations concerning a scenario that has been presented to me.
My company is attempting to obtain company X's Internet transit traffic, which will be BGP-4
over either a T-3 or OC-3. Due to financial reasons, my upper management has proposed that I route company X's Internet traffic via a specific NSP that we
with, we'll call them NSP-A. Apparently, NSP-A has a substantially cheaper rate than our other upstrem providers and it is anticipated that this customer will be sending a full T3 or OC-3's worth of
to us.
Redirecting inbound traffic to company X via NSP-A can be accomplished very easily through use of AS path prepending, however, coming up with a solution for egress traffic from company X to NSP-A, via our AS, has proven a bit more challenging :-).
The only feasible solution that I've been able to come up with is to stick customer X directly on the router that peers with NSP-A and employ the use of policy routing, which would enable me to set the next hop for company X's traffic to the peering address on NSP-A.
Our NSP-A peering router is a Cisco 12016, running IOS 12.0(16)S2 and it has 256MB of DRAM.
Additionally, it is configured with NetFlow and dCEF switching.
I've never employed policy routing in this type of environment and I am concerned about the overhead
it might place on the router or on the traffic traversing the interface.
I've also thought about MPLS TE, however, our core backbone does not run MPLS and even if we did, I believe I would still have to policy route the
USA peering peer traffic that traffic
to NSP-A once the MPLS label was popped off the last router in the path in transit to the NSP-A peering router.
Any ideas or comments would be greatly appreciated.
Thanks in advance,
Jeff
