Prerequisites for Implementing OSPF
The following are prerequisites for implementing OSPF on Cisco IOS XR software:
•
You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment
is preventing you from using a command, contact your AAA administrator for assistance.
•
Configuration tasks for OSPFv3 assume that you are familiar with IPv6 addressing and basic
configuration. See the Implementing Network Stack IPv4 and IPv6 on Cisco ASR 9000 Series Router
module of the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services
Configuration Guide for information on IPv6 routing and addressing.
•
Before you enable OSPFv3 on an interface, you must perform the following tasks:
◦
Complete the OSPF network strategy and planning for your IPv6 network. For example, you must
decide whether multiple areas are required.
◦
Enable IPv6 on the interface.
