Configuring SNMP, BOOTP, DHCP, and RARP Services

4-2

To use RARP services, you must set up a MAC address-to-IP address mapping

table. This table lists the MAC addresses of clients and the corresponding IP

addresses that the RARP server should assign to those clients. When a client

needs to acquire an IP address, the following interchange takes place:

1. The client broadcasts a RARP request specifying its MAC address.

2. Upon receiving a RARP request, the router refers to its MAC address-to-IP

address mapping table, then sends the client a response packet containing the

corresponding IP address.

3. The client examines the response packet to learn its IP address.

You can conﬁgure RARP support on Ethernet, Token Ring, and Fiber Distributed

Data Interface (FDDI) interfaces.

Enabling RARP Services

This section describes how to enable IP and RARP services simultaneously. If you

want to add RARP to a circuit on which you have already conﬁgured IP, refer to

Conﬁguring Routers or Conﬁguring Customer Access and Trunks (BNX

Software), depending on the type of installed software, for information on adding

a protocol.

When you enable RARP services, you are required to conﬁgure only a few

parameters. The Conﬁguration Manager supplies default values for the remaining

parameters.

This section assumes that you have read Conﬁguring Routers or Conﬁguring

Customer Access (BNX Software), depending on the type of installed software,

and that you have

1. Opened a conﬁguration ﬁle

2. Speciﬁed router hardware if this is a local mode conﬁguration ﬁle

3. Selected the link or net module connector on which you are enabling IP

services, or conﬁgured a WAN circuit if this connector requires one
