Since you're concerned about redundancy, have you verified that the two
providers you have selected are using different physical media to transport
your data to the US? Fiber seems to be grossly incestuous up here with
telcos leasing bandwidth to other telcos. The redundancy you think you're
getting may not be as redundant as you think. Something else to check on in
your quest for a solution...

Subject: Re: Load Balancing... [7:14865]
Peter,
Here is the "problem i am trying to solve"
- I am located in Canada
- We have a data center in US. All our users use SAP, Web, FTP, and other
such applications across the border
- We currently have one T1 circuit running to the US
- After monitoring Traffic flow and Utilization we have come to the
conclusion that the bandwisth is not adequate, and that we have no
redundancy
- We have decided to go with 4 links (from 2 different vendors)
- We use OSPF in Canada.
- All unknown routes (0.0.0.0 0.0.0.0) are pushed to the "US router"
I was thinking of doing the following
- Terminating all of these links into one router, and use "per-packet" load
balancing to push these packets across the border
- Use the following config
! disable fast switching
no ip route-cache
no ip mroute-cache
! Use route statements to do per-packet load balancing
ip route 0.0.0.0 0.0.0.0 link1
ip route 0.0.0.0 0.0.0.0 link2
ip route 0.0.0.0 0.0.0.0 link3
ip route 0.0.0.0 0.0.0.0 link4
My only worry is that with the above solution; I will be acheiving
"per-packet" load balancing, but at the cost of a single point of failure
(the Router)....
All suggestions are welcome... Thanks a lot guys,
Santosh Koshy
