Router Functions - Samsung OfficeServ 7100 series System Description

IGMP Snooping
L2 switch (located in the lower layer of the IP router) without the IGMP (Internet Group
Management Protocol) function is located between the IP router and multicast group
member (host), intercepts the IGMP message. And then the L2 switch operates in the IP
router like the group member and operates in the group member like the IP router, which is
referred as the IGMP Snooping. The IP layer multicast group information included in the
IGMP message is reflected in the MAC filtering database, its own switching database.
The group information is processed in the MAC multicast address format mapped with the
IP multicast address.
802.1x Supported
IEEE 802.1x Standards defines the formats and the operation procedures of EAP over LAN
(EAPoL) frame that can send/receive the Extensible Authentication Protocol (EAP)
between terminals and Access Point (AP). These standards are called the port security
protocol because they can be used in the procedure permitting the network access of the
terminal only by acquiring the physical port license of Bridge or wireless AP from the
authentication server. This performance of the authentication procedure by ports enables
the control of charging policies, usage restriction, or band allocation, etc separately by
ports.

4.3.2 Router Functions

Static Routing
OfficeServ 7100 configures the fixed routing table between each network interface to
process the static routing. In this case, the routing table cannot be dynamically changed by
the routing protocol, and specific routing services will be provided according to the pre-set
routing policy.
WAN Interface (Ethernet, PPPoE, DHCP Client)
WAN Interface enables the connection to internet by using the Static IP, PPPoE, DHCP
client protocol.
Routing Protocol
OfficeServ 7100 supports the routing information-exchanging protocol to react on the
network environmental change and to effectively process the routing.
 Routing Information Protocol version1 (RIPv1) and RIPv2
These protocols are widely used for managing the routing information in the mid-
small sized independent network such as a group of LANs.
Open Shortest Path First version2 (OSPFv2)

This routing protocol is used prior to the RIP in the large-size 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.
