Configuring OSPF
Configuring OSPF on a router requires several steps. Depending on your requirements, you may not need
to perform all of the steps listed below.
to perform all of the steps listed below.
By default, OSPF is disabled on the router. Configuring OSPF consists of these tasks:
• Set up the basics of the OSPF network by configuring the required VLANs, assigning ports to the
VLANs, and assigning router identification numbers to the routers involved. This is described in
.
• Enable OSPF. When the image file for advanced routing (Hadvrout.img) is installed, you must load
the code and enable OSPF. The commands for enabling OSPF are described in
• Create an OSPF area and the backbone. The commands to create areas and backbones are described in
• Set area parameters (optional). OSPF will run with the default area parameters, but different networks
may benefit from modifying the parameters. Modifying area parameters is described in
.
• Create OSPF interfaces. OSPF interfaces are created and assigned to areas. Creating areas is described
in
, and assigning areas is described in
.
• Set interface parameters (optional). OSPF will run with the default interface parameters, but different
networks may benefit from modifying the parameters. Also, it is possible to set authentication on an
interface. Setting interface authentication is described in
interface. Setting interface authentication is described in
, and
modifying interface parameters is described in
• 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
• Create a redistribution policy (optional). A redistribution policy allows for the control of how routes
are advertised into OSPF from outside the Autonomous System. Once a policy is created, redistribu-
tion must be enabled. Creating a redistribution policy is described in
tion must be enabled. Creating a redistribution policy is described in
• Create redistribution filters (optional). A redistribution filter controls whether routes are advertised in
the OSPF network. Creating a redistribution filter is described in
• Configuring router capabilities (optional). There are several commands that influence router operation.
• Creating static neighbors (optional). These commands allow you to statically configure neighbors. See
• Configuring redundant switches in a stack for graceful OSPF restart (optional). Configuring stacks
with redundant switches for graceful restart is described in
.
At the end of the chapter is a simple OSPF network diagram with instructions on how it was created on a
router-by-router basis. See
