VRRP (Virtual Router Redundancy Protocol)
The VRRP is a Hot Standby function securing the end-host‟s communication path via the
identical Ethernet‟s backup router in case the main router stops functioning properly.
Routing Protocol
The OfficeServ 7200 supports the routing information-exchanging protocol to react on the
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 network.
A router detects and reports any change in the routing table or the network to other
routers. In this way, all routers share the same routing information.
IGMPv2 Interface

This is an Internet protocol that 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-specified other IP terminals or Internet computers.

The multicasting is used for modifying the address book of the mobile computer users
at the site, sending the company‟s document according to the distribution list, setting
the multicast membership group and broadcasting the broadband width-program of the
streaming media to the audience tuning the received wavelength.
Routing Between the VLAN Groups
The communication between the VLAN groups is done through the routing between the
VLAN groups.
CBQ/BoD (Bandwidth on Demand)
The queuing process is differentially performed according to the level table where the
routing process priority for a data server is defined.
RTP Priority
The Real-Time Transport Protocol (RTP) packet is a VoIP media packet.
The queuing process for the RTP packet is prior to that of other data packets, which helps
to maintain the tone quality. This function is useful when using the VoIP function in the
network where the VoIP packet that should be processed in real time and other packets for
general office work are mixed processed.
