I have traffic engineering between 2 routers. There are 3 direct links and I need to offload some traffic over a different path due to that the traffic volume is exceeding 30G at some time of the day.
I have allocated 9,9G to each of the direct paths and 1G to each of the 8 indirect paths.
According to cef it should "serve" tunnel1013-1015 8 times more often than tunnel1027-1034
I expect to have 78% over the direct path and 22% over the indirect path but when monitoring the tunnels I see that 60% goes over direct path and 40% over indirect path.
Can anyone see a reason for this?
