When this option is set to On (def), the Express 6100/6120 bridge func-
tion will be enabled. Setting it to Off will disable all bridge function-
ality.
»» Bridge/WAN IP Bridge
When IP routing is active, the Express 6100/6120 will allow another
WAN device to bridge IP packets to it using PPP BCP. Normally, two
IP routers would negotiate PPP IPCP to exchange IP packets. Howev-
er, if a device can only support PPP BCP, IP packets are encapsulated
by the device as bridge packets. The Express 6100/6120 can treat the
WAN IP Bridge as a virtual Ethernet port connected only to a WAN
device which has negotiated PPP BCP. This menu allows the IP pa-
rameters for this virtual Ethernet to be set up.
