??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/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 section.
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.
