Router Role

3 Router Role

The Router or BRAS plays an important role in the Shared DSL concept, and must perform the following functions:

DHCP requests from the IP DSLAM in the remote site must be relayed towards the EDA network, using the management VLAN ID.

The Management PVC from the remote site must be mapped to the EDA Management VLAN.

If PPPoE or PPPoA is used for the END-user traffic, it must be terminated by the BRAS.

If the Router (or BRAS) is not an Edge Node of the EDA network as well, a tunnel must be established to the EDN network (for example L2TP or another VPN solution, see Figure 2 on page 5).
