ZyXEL Communications 642R Series manual IP Multicast, IP Policy Routing Ippr, Protocols Supported

Prestige 642R Series ADSL Router

zIP Multicast

Traditionally, IP packets are transmitted in two ways: unicast or broadcast. Multicast is a third way to deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC2236). Both versions 1 and 2 are supported by the Prestige

zIP Policy Routing (IPPR)

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.

z10/100M Fast Ethernet LAN Interface

The P642's 10/100M auto-negotiating LAN interface enables fast data transfer of either 10Mbps or 100Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.

zProtocols Supported

‹TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.

‹PPP (Point-to-Point Protocol) link layer protocol.

‹SUA™ (Single User Account) and NAT (Network Address Translation).

zMultiple Protocol Support

♦Novel IPX (Internetwork Packet eXchange) network layer protocol.

♦Transparently bridging for unsupported network layer protocols.

zDHCP Support

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has the built-in DHCP Server enabled by default. DHCP Relay allows the Prestige to act as a surrogate DHCP server where it relays IP address assignment from the actual DHCP server to its clients.

zMultiple PVC (Permanent Virtual Circuits) Support

Your Prestige supports up to 8 PVC’s.

zNetworking Compatibility

Your Prestige is compatible with the major ADSL DSLAM (Digital Subscriber Line Access Multiplexer) providers, making configuration as simple as possible for you.

zMultiplexing

The Prestige 642R Series supports VC-based and LLC-based multiplexing.

zEncapsulation

The Prestige 642R Series supports PPP (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM, MAC encapsulated routing as well as PPP over Ethernet (RFC 2516).
