ARP

Address Resolution Protocol (ARP) is used to resolve an IP address into a data link layer address.

l ARP configuration

l Gratuitous ARP configuration

l ARP source suppression configuration

l Proxy ARP configuration

DHCP

DHCP is built on a client-server model, in which the client sends a configuration request and then the server returns a reply to send configuration parameters such as an IP address to the client.

l DHCP server configuration

l DHCP relay configuration

DNS

Domain Name System (DNS) is a distributed database used by TCP/IP applications to translate domain names into corresponding IP addresses.

l Configuration of static domain name resolution

l Configuration of dynamic domain name resolution

l DNS proxy configuration

IP Addressing

l IP address configuration

l Configuration of IP unnumbered

IP Performance

In some network environments, you need to adjust the IP parameters to achieve best network performance.

l Configuration of the maximum TCP segment size (MSS) of the interface

l Configuration of SYN cookie feature and protection against Naptha attack

l TCP optional parameters configuration

l Configuration of ICMP to send error packets

UDP Helper

UDP Helper is to relay specified UDP packets. In other words, UDP Helper functions as a relay agent that converts UDP broadcast packets into unicast packets and forwards them to a specified destination server.

l UDP Helper configuration

URPF

Unicast Reverse Path Forwarding (URPF) protects a network against attacks based on source address spoofing.

l Introduction to basic URPF concepts

l URPF processing flow

l URPF configuration

IPv6 Basics

Internet Protocol Version 6 (IPv6), also called IP next generation (IPng), was designed by the Internet Engineering Task Force (IETF) as the successor to Internet Protocol Version 4 (IPv4).

l Basic IPv6 functions configuration

l IPv6 Neighbor Discovery Protocol (NDP) configuration

l PMTU discovery configuration

l IPv6 TCP properties configuration

l Configuration of IPv6 FIB-based forwarding

l Configuration of ICMPv6 packets sending

l IPv6 DNS configuration

Dual Stack

A network node that supports both IPv4 and IPv6 is called a dual stack node. A dual stack node configured with an IPv4 address and an IPv6 address can have both IPv4 and IPv6 packets transmitted.

l Dual stack configuration

Tunneling

Tunneling is an encapsulation technology, which utilizes one network transport protocol to encapsulate packets of another network transport protocol and transfer them over the network.

l Configuration of IPv6 manual tunnel

l Configuration of automatic IPv4-compatible IPv6 tunnel

l 6to4 tunnel configuration

l ISAPTAP tunnel configuration

l IPv4 over IPv4 tunnel configuration

GRE

Generic Routing Encapsulation (GRE) is a protocol designed for performing encapsulation of one network layer protocol (for example, IP or IPX) over another network layer protocol (for example, IP).

l GRE tunnel configuration

Adjacency Table

An adjacency table manages the information on the neighbors that are both connected and active.
