PPPoA = Point to Point Protocol over ATM (Asynchronous Transfer Mode)
PPPoE = Point to Point Protocol over Ethernet
Bridge = Bridge Protocol
Classical IPoA = Internet Protocol over ATM (Asynchronous Transfer
Mode). This is an ATM encapsulation of the IP protocol.
Bridge Broadcast
Factory Default = CHECKED
When this setting is CHECKED, the Router will allow Broadcast IP packets
to/from the WAN.
When this setting is NOT CHECKED, the router will block Broadcast IP
packets to/from the WAN.
This setting is only valid if one of the Virtual Channels is configured for
Bridge mode.
Bridge Multicast Factory Default = CHECKED
When this setting is CHECKED, the Router will allow Multicast IP packets
to/from the WAN.
When this setting is NOT CHECKED, the Router will block Multicast IP
packets to/from the WAN.
This setting is only valid if one of the Virtual Channels is configured for
Bridge mode.
Spanning Tree Protocol Factory Default = DISABLED
Spanning Tree Protocol is a link management protocol that provides path
redundancy while preventing undesirable loops in the network. For Ethernet
network to function properly, only one active path can exist between two
stations.
When ENABLED, two bridges are used to interconnect the same two
computer network segments. Spanning Tree Protocol will allow the bridges to
exchange information so that only one of them will handle a given message
that is being sent between two computers within the network.
