Routing Protocol
The OfficeServ 7400 supports the routing information-exchanging protocol to react on the
network environmental change and to effectively process the routing.
y Routing Information Protocol version1 (RIPv1), RIPv2
These protocols are widely used for managing the routing information in the middle-size
independent network such as a group of LANs.
y 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.
y BGP4 (Border Gateway Protocol 4)
As an Exterior Gateway Protocol through which Autonomous System (AS) sends/receives
the routing information between other networks, the Version 4 of BGP is currently used.
BGP4 uses various matrixes when selecting the optimized path to the destination. BGP4
compares each matrix having priority and selects the optimized path.
Routing Protocol
The OfficeServ 7400 supports the routing information-exchanging protocol to react on the

y RIPv1 (Routing Information Protocol version1), RIPv2, RIPng
These protocols are widely used for managing the routing information in a middle-sized
independent network such as a group of LANs.
y OSPFv2 (Open Shortest Path First version2), OSPFv3
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.
y BGP4 (Border Gateway Protocol 4), BGP4+
This is the Exterior Gateway Protocol that the AS (Autonomous System) uses to
send/receive routing information to/from other networks. The current BGP is use is
version 4. The BGP4 uses diverse metrics to select the best path to the destination;
each metric will be referenced following the priority order to provide the best path.
GRE Tunnel (Generic Routing Encapsulation)
The GRE Tunneling creates a virtual tunnel to provide a logical, non-physical path. A GRE
tunnel over IPSec method, interconnected with the VPN, is used for general purposes.
In this case, the original IP header and the payload is encapsulated/encrypted to ensure
confidentiality.
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.
