Prestige 1600 Universal Access Concentrator
5-4 I
nternet Access
The Prestige supports both IGMP version 1 (IGMP-v1) and IGMP-v2. At start up, the Prestige queries all directly
connected networks to gather group membership. After that, the Prestige periodically updates this information by
sending a membership query to 224.0.0.1. IP Multicasting can be enabled/disabled on the Prestige LAN and/or
WAN interfaces using menus 3.2 (LAN) and 11.3 (WAN). Select None to disable IP Multicasting on these
interfaces.
5.3 IP Policies
Traditionally, routing is based on the destination address only and the router takes the shortest path to forward a
packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior and alter the
packet forwarding based on the policy defined by the network administrator. Policy-based routing is applied to
incoming packets on a per interface basis, prior to the normal routing. Create policies using SMT Menu 25 (see the
IP Policy Routing chapter) and apply them on the Prestige LAN and/or WAN interfaces using menus 3.2 (LAN)
and 11.3 (WAN).
5.4 TCP/IP Ethernet Setup
To edit Menu 3.2, select Menu 3 Ethernet Setup in the Main Menu and then the appropriate LAN. Then select the
submenu option 2, and press [ENTER]. The screen now displays Menu 3.2 - TCP/IP Ethernet Setup as shown
next.
