5.2.6.2 Soft GRE
In soft GRE, only one side of the tunnel needs to be configured; the other end learns
the remote IP addresses of all remote tunnel endpoints by examining the incoming
GRE packets.
GRE tunnels can be automatically created when devices attach to the AP,
eliminating the need for each AP to be explicitly provisioned on the WLAN Gateway.
Because this soft GRE is stateless and the tunnel contexts are created based on
need, the WLAN Gateway does not need to maintain states for unused tunnels,
which improves scalability.
The operator can restrict the traffic going through the GRE tunnel based on the
SSIDs or LAN ports.
Figure 14 illustrates the soft GRE architecture.
Figure 14 SoftGRE-based architecture
For more information about soft GRE architecture and configuration procedures, see
the 7368 Configuration, Management, and Troubleshooting guide, which contains
the vCPE User Guide.
Note — While the vCPE forwards all traffic over the GRE
tunnel, the soft GRE architecture for the G-120W-F enables the
operator to restrict the traffic over the GRE tunnel bases on
SSIDs or LAN ports.
