ARP

Address Resolution Protocol (ARP) is used to resolve an IP address into a data link layer address. ARP configuration involves mainly the following tasks:

l      Configuring ARP

l      Configuring gratuitous ARP

l      Configuring proxy ARP

IP performance

In some network environments, you need to adjust the IP parameters to achieve best network performance. IP performance configuration involves mainly the following tasks:

l      Enabling the device to receive and forward directed broadcasts

l      Configuring TCP attributes, such as TCP timers, buffer size, packet size, and ICMP error packet sending

l      Configuring the maximum segment size (MSS) of the interface

l      Configuring the device to/not to send ICMP error messages

IP unicast policy routing

Policy routing is a mechanism that implements route selection based on the user-defined policies. Policy routing configuration involves the following task:

l      Configuring IP unicast policy routing

Adjacency table

An adjacency table manages the information on the neighbors that are both connected and active, such as network layer address (next hop), route outgoing interface, link layer service type, and link layer address.

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). Perform the following tasks to configure IPv6:

l      Configuring basic IPv6 functions

l      Configuring the IPv6 Neighbor Discovery Protocol (NDP)

l      Configuring path MTU (PMTU) discovery

l      Configuring IPv6 TCP properties

l      Configuring IPv6 FIB-based forwarding

l      Specifying the maximum number of ICMPv6 error packets sent in an interval

l      Configuring IPv6 DNS
