1.6.1 Example for Configuring Link Aggregation in Manual Load
Balancing Mode
Networking Requirements
As shown in Figure 1-4, the Router is connected to the broadband remote access server (BRAS)
through an Eth-Trunk. The link between the Router and BRAS must ensure high reliability, and
data traffic needs to be load balanced among the LPUs of the Router. To meet this requirement,
you need to configure an Eth-Trunk on the Router.
