Configuring OSPFv3
Configuring OSPFv3 on a router requires several steps. Depending on your requirements, you may not
need to perform all of the steps listed below.
By default, OSPFv3 is enabled on the router. Configuring OSPFv3 consists of these tasks:
• Set up the basics of the OSPFv3 network by configuring the required VLANs, assigning ports to the
VLANs, and assigning router identification numbers to the routers involved. This is described in
“Preparing the Network for OSPFv3” on page 2-14.
• Load OSPFv3. When the image file for advanced routing is installed, you must load the OSPFv3 code.
The commands for loading OSPFv3 are described in “Activating OSPFv3” on page 2-14.
• Create any desired OSPFv3 areas, including the backbone area if one is required. Note that a backbone
area is not necessary if there is only one area. The commands to create areas and backbone areas are
described in “Creating an OSPFv3 Area” on page 2-15.
• Set area parameters (optional). OSPFv3 will run with the default area parameters, but different
networks may benefit from modifying the parameters. Modifying area parameters is described in
“Configuring Stub Area Default Metrics” on page 2-16.
• Create OSPFv3 interfaces. OSPFv3 interfaces are created and assigned to areas. Creating interfaces is
described in “Creating an Interface” on page 1-20, and assigning interfaces is described in “Assigning
an Interface to an Area” on page 1-20.
• Set interface parameters (optional). OSPFv3 will run with the default interface parameters, but differ-
ent networks may benefit from modifying the parameters. Also, it is possible to set authentication on
an interface.
• Configure virtual links (optional). A virtual link is used to establish backbone connectivity when two
backbone routers are not physically contiguous. To create a virtual link, see “Creating Virtual Links”
on page 2-17.
• Configure redistribution using route maps (optional). Redistribution allows the control of how routes
are advertised into the OSPFv3 network from outside the Autonomous System. Configuring redistribu-
tion is described in “Configuring Redistribution” on page 2-18.
• Configure router capabilities (optional). There are several commands that influence router operation.
These are covered briefly in a table in “Configuring Router Capabilities” on page 2-24.
At the end of the chapter is a simple OSPFv3 network diagram with instructions on how it was created on
a router-by-router basis. See “OSPFv3 Application Example” on page 2-25 for more information.
