Basic IPv6 Configurations
The IPv6 protocol stack supports routing protocols and application protocols on an IPv6 network.
- IPv6 Overview
Internet Protocol Version 6 (IPv6), also called IP Next Generation (IPng), is the second-generation Internet Protocol. It is a set of specifications defined by the Internet Engineering Task Force (IETF). - IPv6 Features Supported by the Device
Basic IPv6 functions include IPv6 address configuration, rate limiting for sending ICMPv6 error packets, IPv6 neighbor discovery (ND), path maximum transmission unit (PMTU) discovery, and Transmission Control Protocol for IPv6 (TCP6). - Default Configuration
This section describes the default IPv6 configuration. - Configuring IPv6 Addresses for Interfaces
To enable network devices to communicate at the network layer, configure interface IPv6 addresses on the network devices. - Configuring ICMPv6 Error Packet Control
Configuring ICMPv6 error packet control reduces network traffic and prevents malicious attacks. - Configuring IPv6 Neighbor Discovery
The Neighbor Discovery Protocol (NDP) is a basic IPv6 protocol. It replaces the Address Resolution Protocol (ARP) and ICMP Router Discovery on an IPv4 network. Additionally, IPv6 ND provides redirection and neighbor unreachability detection. - Configuring PMTU
When the device functions as the source node and sends IPv6 packets to the destination node, the device fragments packets based on PMTU. The intermediate device does not need to fragment packets. This reduces the burden of the intermediate device to effectively use network resources and obtain the maximum throughput. - Configuring TCP6
You can configure TCP6 attributes to improve network performance. - Maintaining IPv6
Maintaining IPv6 includes clearing IPv6 statistics and monitoring IPv6 running status. - Configuration Examples
This section provides IPv6 configuration examples, including networking requirements and configuration roadmap.
