| # In this example we have 3 wan links (vlanXXX interfaces) attached to a single |
| # physical interface because we use a vlan-enabled switch between the balancer |
| # machine and the ADSL routers we want to balance. The weight parameter should |
| # be kept to a low integer, in this case the ADSL line connected to vlan101 and |
| # vlan102 is 4Mbps and the ADSL line connected to vlan100 is 8Mbps (twice fast) |
| # so the WEIGHT value in vlan100 is 2 because it is two times faster. |
| # be kept to a low integer. |
