D-Link DI-308 Network Router User Manual


 
DI-308 ISDN Remote Router
55
The parameters are described below:
IP Address
– This is a network IP address of a separate IP network on the LAN.
Routing Protocol
– This is the same as in the
Network Configuration
section.
Keep in mind that these exchanges are made with adjacent routers on the LAN, if
present.
IP Multicasting
– This enables or disables IP multicasting on the IP network you
are defining.
All other parameters (Netmask, Routing Mode, Multicast Protocol and IGMP
Version) are identical to those in the
Network Configuration
,
IP Stack
Configuration
,
ISDN
screens.
Static ARP
This special function is intended to speed up the process of finding a host's Ethernet
(MAC) address from its network address, and provides a special condition – any
other host acting as an impostor by using the same IP address as the legitimate host,
will be ignored by this router.
Basically, when a packet comes into the router from the ISDN line and is destined
for a host on the LAN, the router will use information defined here to immediately
send the packet to the host rather than send out an ARP request to find the host’s
MAC address.
