2.1.7 Layer III Routing Features

IP Routing

The PRIMERGY BX600 IP Routing layer (IPv4 support) contains the IP Forwarding layer,
Address Resolution Protocol (ARP) Mapping Layer, and Routing Table Object (RTO).
PRIMERGY BX600 also provides that each port which is be configured to participate in the
routed network.
The IP Routing layer provides the following functions:
ARP Mapping (Table)/Static ARP
For maintaining the ARP Table used to correlate IP and MAC addresses. The table
contains both static entries configured by user and entries dynamically updated based on
information in received ARP frames.
Static ARP can be defined in the ARP table. When static entries are defined, a permanent
entry is entered and is used to translate IP address to MAC address.
Routing Table Object (RTO)
The Routing Table Object manages a common routing table for all registered routing
protocols.
IP Forwarding Layer
The IP Forwarding layer forwards received IP packets that cannot be forwarded through
the hardware.

Routing Information Protocol (RIP)

The Routing Information Protocol, or RIP, has been a long-standing protocol used by
routers for exchanging route information. RIP is a distance vector protocol whereby each route
is characterized by the number of gateways, or hops, a packet must traverse to reach its
intended destination. RIP categorized as an interior gateway protocol and operates within the
scope of an autonomous system.
RIP is designed such that its routers send the contents of their routing table every 30
seconds to each adjacent router. These periodic updates allow routes to remain active in the
route table; absence of a route from the updates causes the route to be declared unusable
after 180 seconds have elapsed, and to be removed from the table after an additional 120
seconds passes without the route appearing in an update message.
Two versions of RIP are in current use:
RIPv1 defined in RFC 1058
- The RIP routing messages are specified by IP destination network and hop count and not
include the concept of subnets.
- The RIP routing messages are broadcast to all stations on the attached network.
