Provides comprehensive instructions for configuring and managing IP addressing, traffic control, address resolution, host and transport services, forwarding behavior, and gateway redundancy features across IPv4 and IPv6 network stack deployments.
Getting Started
Outlines the release history and update summary for the IP Addresses and Services Configuration Guide. It enables users to access the latest IOS XR features and release information through a centralized, continuously updated resource.
Network Stack IPv4 and IPv6 Addressing
Summarizes IPv4 and IPv6 network stack capabilities, address formats, scaling, interface addressing, protocol processing, virtual addressing, ICMP controls, and flexible source IP configuration.
Network Stack Traffic Control and Address Management
Summarizes IPv6 path MTU controls, TCP MSS adjustment, neighbor discovery, IP address conflict resolution, VRF fallback, redirects, and local station MAC address configuration.
Address Resolution
Summarizes ARP address resolution, cache entries, proxy behavior, cache management controls, duplicate packet policing, and direct-attached gateway redundancy configuration guidance.
Dynamic Host Configuration Protocol
This chapter groups the concepts, tasks, and reference material required to implement Dynamic Host Configuration Protocol (DHCP) on the Cisco 8000 Series Router.
Host Services and Applications
Describes the router services and applications used to diagnose network paths, resolve hostnames, transfer files, provide network access, identify syslog traffic, and configure HTTP client behavior.
Introduction to Access Control Lists
This chapter introduces access control lists (ACLs), covering how sequence numbering works, how to apply ACLs, and the tasks to configure IPv4, IPv6, and extended ACLs on the Cisco 8000 Series Router.
Hybrid and object-group ACLs
This chapter describes hybrid ACLs and object-group ACLs on the Cisco 8000 Series Router, including network and port object-group configuration, compression verification, and 24-bit bincode support for egress object-group ACLs.
Network protocol and interface integration
This chapter describes how to integrate ACLs with network protocols and interfaces on the Cisco 8000 Series Router, including use in class maps, inline action modifications, bridge virtual interfaces, Layer 2 interfaces, ACL-based forwarding, and internal VRF-based forwarding.
Diagnostic, statistics, and policy control
This chapter describes diagnostic and statistics features for ACLs on the Cisco 8000 Series Router, including user-defined TCAM keys, ACL counters and statistics, fragment control, packet length filtering, TTL matching, logging, and per-interface statistics.
Cisco Express Forwarding
Describes CEF operation, route programming, forwarding scale, load distribution, and diagnostics. Provides requirements and tasks for configuring and verifying supported forwarding features.
Local Packet Transport Services
Explains LPTS packet delivery, flow capacity, policers, NPU traps, and control and management plane ACLs. Provides configuration, monitoring, verification, tuning, and traffic-filtering guidance for protecting router-bound traffic.
Implement VRRP
Describes how to implement the Virtual Router Redundancy Protocol (VRRP) to enable transparent failover at the first-hop IP router by allowing a group of routers to act as a single virtual router.
Implement HSRP
Describes how to implement the Hot Standby Router Protocol (HSRP) to provide transparent failover at the first-hop IP router by allowing a group of routers to act as a single virtual router.
Transport Protocol Operations
Summarizes TCP, UDP, and RAW transport behavior, NSR session preservation, failover recovery, and TCP dump file inspection and conversion for troubleshooting.
