ARP

2

Even though IP packets are addressed using IPaddresses, hardware addresses must be used toactually transport data from one host toanother. Address Resolution Protocol is used to

map OSI level 3 IP addresses to OSI level 2 MACaddresses. Router has a table of currently usedARP entries. Normally the table is builtdynamically, but to increase network security, it

can be partially or completely built statically bymeans of adding static entries.

Note: Maximum number of ARP entries are 8192.

● Enabled

● Disabled

● Reply-Only

ARP Mode

8

● EnabledThis mode is enabled by default on all

interfaces. ARPs will be discovered

automatically and new dynamic entries willbe added to ARP table.




ARP Mode

9

● DisabledIf 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 OnlyIf arp property is set to reply-only on the

interface, then router only replies to ARP

requests. Neighbour MAC addresses will beresolved 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.

DHCP Server

●The Dynamic Host Confirmation Protocol

(DHCP) service enables devices on a network to

obtain IP addresses and other information from

a DHCP server. This service automates the

assignment of IP addresses, subnet masks,gateway and other IP networking parameters.

● In order for the DHCP server to work, IP pools

must also be configured (do not include theDHCP server's own IP address into the pool

range) and the DHCP networks.

NTP Client

Why NTP?

● To get correct time on router.

● To get time for routers has no internalmemory to save clock time.

NTP Client




34

User and Group

● MikroTik’s default username is admin with no

password.

● There are three different groups with different

permission level. The groups are:

1. Full2. Read

3. Write

Username, password and Group can be added,

removed or changed as per requirements
