Lists the essential requirements you must meet before configuring OSPF on Cisco IOS XR routers.
Requirements
The following requirements apply before you configure OSPF on Cisco IOS XR routers:
-
User group assignment: You must belong to a user group associated with a task group containing the required task IDs to enable OSPF commands. See the command reference for task ID details. Contact your AAA administrator if you encounter command restrictions.
-
OSPFv3 and IPv6 familiarity: You should be familiar with IPv6 addressing and basic network configuration before configuring OSPFv3. For more information, see the "Implementing Network Stack IPv4 and IPv6" module.
-
Interface preparation for OSPFv3: Complete your OSPF network strategy and IPv6 planning before enabling OSPFv3 on interfaces. Decide if multiple OSPF areas are required, and make sure IPv6 is enabled on each interface.
-
Authentication configuration (optional): If you plan to enable authentication (IP Security), choose between plaintext or Message Digest 5 (MD5) authentication, and determine whether authentication applies to an entire area or to specific interfaces.
Use these requirements as a reference when planning, configuring, or validating OSPF on Cisco IOS XR routers.
