APPLICATION

PENGERTIAN
NAME SYSTEM
DNS
 ð Translates domain names,such as cisco.com, into IP   addresses


HOST CONFIG
BOOTP
 ð  Enables a diskless workstation to discover its own IP address,the IP address of a BOOTP server on the network,and a file to be loaded into memory to boot the machine

 ð  BOOTP is being superseded by DHCP
DHCP
 ð  Dynamically assigns IP addresses to client stations at start-up

 ð  Allows the addresses to be re-used when no longer needed

 ð  Open standard interior routing protocol
EIGRP
 ð  Cisco Proprietary Routing Protocol
 ð  Uses Composite metric based on bandwidth,delay,load,reliability and MTU
BGP 
 ð  BGP4 latest version
 ð  External Routing used between Autonomous Systems

NETWORK ACCESS
ARP
 ð  Provides dynamic address mapping between an IP address and a hardware address
PPP
 ð  Provides a means of encapsulating packets for transmission over a serial link
ETHERNET
