Configuration procedures for OSPFv3

To begin using OSPFv3 on the routing switch:

  1. Enable IPv6 on at least one VLAN interface.
  2. In the global config context, use ipv6 unicast-routing to enable routing
  3. Execute router ospf3 enable to enable OSPFv3 routing.
  4. Use area in the ospf3 context to assign the areas to which the routing switch will be attached.
  5. Assign VLAN interfaces to the configured areas by moving to each VLAN context and using the command ipv6 ospf3 area ospf-area-id assigns all interfaces in the VLAN to the same area.
  6. Optional: Assign loopback interfaces to OSPFv3 areas by using the interface loopback 0 - 7 ipv6 ospf3 area command.
  7. Optional: On each routing switch used as an ASBR in your OSPFv3 domain:
    1. Configure route-maps to permit route prefixes you want redistributed in your OSPFv3 domain and to deny all others.

    2. Configure redistribution to enable importing the static and connected routes you want to make available in the domain.

  8. Optional: Configure ranges on ABRs to reduce inter-area RA.
  9. Optional: Use administrative distance to influence route choices.
  10. Optional: Enforce strict LSA operation for graceful restart helper mode.
  11. Optional: Adjust performance by changing the IP routing interface settings, if needed. Includes cost, dead-interval, hello-interval, and priority commands.
  12. Configure virtual links for any areas not directly connected to the backbone.
