Summarizes IPv4 and IPv6 network stack capabilities, address formats, scaling, interface addressing, protocol processing, virtual addressing, ICMP controls, and flexible source IP configuration.
Use this chapter to understand IPv4 and IPv6 addressing behavior and configure address-related network stack functions on router interfaces.
The chapter organizes IPv4 and IPv6 addressing information into these content areas:
|
Content area |
Included information |
|---|---|
|
Network stack capabilities |
IPv4 and IPv6 functionality, exceptions, host route scale support, and IPv6 prefix scale expansion guidelines. |
|
IPv4 addressing |
Interface and virtual addresses, ICMP rate limiting, unnumbered-interface processing, secondary addresses, and IPv4 packet headers. |
|
IPv6 addressing |
Address space and formats, global and link-local unicast addresses, IPv4-compatible addresses, packet headers, multicast groups, virtual addresses, and flexible source IP. |
The topics progress from network stack capabilities and scale controls to IPv4 addressing and then IPv6 addressing. Requirement and restriction information appears before the related configuration tasks.
Network stack IPv4 and IPv6
Provides comprehensive instructions for configuring and monitoring IPv4 and IPv6 features on interfaces, covering addressing, dual-stack operation, IPv6 Neighbor Discovery behavior, and scaling and address-management options for IPv4 and IPv6 deployments.
How to implement network stack IPv4 and IPv6
Describes IPv4 implementation workflows, including access prerequisites, primary and secondary interface addressing, virtual management addresses, ICMP rate limiting, and unnumbered point-to-point interfaces.
IPv6 addresses
Describes IPv6 interface addressing, including address-space scale, syntax, unicast types, packet headers, multicast groups, virtual management addresses, ICMP rate limiting, dual-stack configuration, and source-address selection.
