1483 Bridged IP VC-Mux in the Encapsulation field.

 

Use this field to enable or disable the bridge mode. Activate the bridge

 

mode when your ISP provides you with more than one IP address and

 

you want the connected computers to get individual IP address from

 

ISP’s DHCP server directly.

Default Route

Select Yes to direct traffic not listed in the routing table to the default

 

gateway.

TCP MTU Option

The Maximum Transmission Unit (MTU) defines the size of the largest

 

packet allowed on an interface or connection. Enter the MTU in this

 

field.

routing information with other routers.

 

Select the RIP version from RIP1, RIP2-Band RIP2-M.

 

 

Direction

Use this field to control how much routing information the P-660RU-Tx

 

sends and receives on the subnet.

 

Select the RIP direction from None, Both, IN Only and OUT Only.

 

 

Multicast

Multicast packets are sent to a group of computers on the LAN and are

 

an alternative to unicast packets (packets sent to one computer) and

 

broadcast packets (packets sent to every computer).

 

IGMP is a network-layer protocol used to establish membership in a

 

multicast group. The P-660RU-Tx supports IGMP v1, IGMP v2 and

 

IGMP v3. Select Disabled to turn off the feature.

This field is only available when you select 1483 Bridged IP LLC or

 

1483 Bridged IP VC-Mux in the Encapsulation field.

 

Select Enable to alter the MAC address that you entered below so

 

that the PVCs on the P-660RU-Tx can establish connections to the

 

network.
