Using Layer 2 Tunnels

Using Layer 2 Tunnels

Layer 2 tunnels use the Layer 2 Tunneling Protocol (L2TP), version 2, to provide 

the following benefits:
• provide a bi-directional communication path between the BelAir20E and a 

central router. The path is unaffected by the size, topology and complexity 

of the Layer 2 and Layer 3 access network between them.

• ensure efficient handling of mobile client MAC addresses, especially for 

customers using DOCSIS technology in their access network

Figure 7

 shows how wireless mobility is implemented with L2TP. When a 

wireless client transmits an 802.11 frame, the BelAir AP converts it to an 

Ethernet frame with VLAN information, encapsulates it within an IP packet and 

then sends the packet to a Tunnel End Point (TEP). The TEP is usually part of a 

network central router. The BelAir implementation of Layer 2 tunnels currently 

operates with a Cisco 7200 router or equivalent, with a RedBack SmartEdge 

router or equivalent., with other routers that use Generic Router 

Encapsulation (GRE), or with Proxy Mobile IPv4 (PMIP) implementations.
