2. ARP

Prepared by- M Abdullah Al Naser (mail.naserbd@yahoo.com)
Even though IP packets are addressed using IP
addresses, hardware addresses must be used to
actually transport data from one host to
another. Address Resolution Protocol is used to
map OSI level 3 IP addresses to OSI level 2 MAC
addresses. Router has a table of currently used
ARP entries. Normally the table is built
dynamically, but to increase network security, it
can be partially or completely built statically by
means of adding static entries.

8. ARP Mode

Prepared by- M Abdullah Al Naser (mail.naserbd@yahoo.com)
● Enabled
This mode is enabled by default on all
interfaces. ARPs will be discovered
automatically and new dynamic entries will
be added to ARP table.

9. ARP Mode

Prepared by- M Abdullah Al Naser (mail.naserbd@yahoo.com)
● Disabled
If ARP feature is turned off on the interface, i.e.,
arp=disabled is used, ARP requests from clients are
not answered by the router. Therefore, static arp
entry should be added to the clients as well. For
example, the router's IP and MAC addresses
should be added to the Windows workstations
using the arp command:

● Reply Only
If arp property is set to reply-only on the
interface, then router only replies to ARP
requests. Neighbour MAC addresses will be
resolved using /ip arp statically, but there
will be no need to add the router's MAC
address to other hosts' ARP tables like in
case if arp is disabled.
