OfficeServ 7200 General Description Guide
WAN Interface (Ethernet, PPPoE, DHCP Client)
The OfficeServ 7200 accesses the Internet through the WAN1 and WAN2 Ethernet
WAN interface using the PPPoE and DHCP client protocols.
V.35 Interface (PPP, HDLC, Frame Relay)
The OfficeServ 7200 accesses the Internet through the V.35 serial interface with a
transfer speed of up to 2Mbps. In this case, the system supports various environ-
ments using functions such as PPP, HDLC and Frame Relay Encapsulation.
Subnet Routing
The WAN1, WAN2, LAN, and DMZ network interfaces are configured with differ-
ent sub-network interfaces, enabling them to perform the routing process with each
other.
Routing Protocol
The OfficeServ 7200 supports the routing information-exchanging protocol to react
to network environmental change and to effectively process the routing.
RIPv1, RIPv2
These protocols are widely used for managing the routing information in a
middle-sized independent network such as a group of LANs.
OSPFv2
This routing protocol is used prior to the RIP in a large-sized independent net
work. A router detects and reports any change in the routing table or the net-
work to other routers. In this way, all routers share the same routing informa-
tion.
IGMPv2 Interface
This Internet protocol enables an IP terminal or an Internet computer to report
multicast groups to nearby routers. The multicasting allows a host computer to
send the contents to pre-specify other IP terminals or Internet computers.
Multicasting is used for modifying the address books of mobile computer users
at the site, sending the company's documents according to the distribution list,
setting the multicast membership group and broadcasting the broadband width-
program of the streaming media to the audience tuning into the received wave
length.
Routing Between VLAN Groups
Communication between the VLAN groups is done through routing between the
groups.
