ND OF STEPS
Example:
Suppose a Gigabit Ethernet interface card is inserted into slot 3
of ZXR10 GER to configure an IP address of second interface as
192.168.3.1 and to set mask code to 255.255.255.0. The
detailed configuration is as follows:
show ip interface command can be used to view an IP address
of the interface.
Configuring ARP
When a piece of network equipment sends data to another piece
of network equipment, physical address (MAC address) of
destination equipment must also be known in addition to IP
address. ARP (Address Resolution Protocol) is used to map IP
addresses into physical addresses to guarantee smooth
communications.
Firstly, source equipment advertises an ARP request containing
an IP address of destination equipment and all types of
equipment on network receives ARP request. If a piece of
equipment finds that IP address in request matches with its own
IP address, this sends a reply containing its MAC address to
source equipment. Source equipment obtains MAC address of
the destination equipment according to reply.
To reduce ARP packets on a network and send data faster,
mapping relation between IP addresses and MAC addresses is
buffered in a local ARP table. When a piece of equipment wants
to send data, this first search an ARP table according to IP
address. If MAC address of destination equipment is found in
ARP table, the equipment no longer sends any ARP request.
Dynamic entries in ARP table deletes automatically after a period
of time. This period of time is called "ARP aging time".
