Configuring OSPF Configuring OSPF

Preparing the Network for OSPF
OSPF operates on top of normal switch functions, using existing ports, virtual ports, VLANs, etc. The
following network components should already be configured:
• Configure VLANs that are to be used in the OSPF network. VLANS should be created for both the
backbone interfaces and all other connected devices that will participate in the OSPF network. A
VLAN should exist for each instance in which the backbone connects two routers. VLAN
configuration is described in “Configuring VLANs” in the OmniSwitch AOS Release 7 Network
Configuration Guide.
• Assign IP interfaces to the VLANs. IP interfaces, or router ports, must be assigned to the VLAN.
Assigning IP interfaces is described in “Configuring IP” in the OmniSwitch AOS Release 7 Network
Configuration Guide.
• Assign ports to the VLANs. The physical ports participating in the OSPF network must be assigned to
the created VLANs. Assigning ports to a VLAN is described in “Assigning Ports to VLANs” in the
OmniSwitch AOS Release 7 Network Configuration Guide.
• Set the router identification number. (optional) The routers participating in the OSPF network must
be assigned a router identification number. This number can be any number, as long as it is in standard
dotted decimal format (e.g., 1.1.1.1). Router identification number assignment is discussed in
“Configuring IP” in the OmniSwitch AOS Release 7 Network Configuration Guide. If this is not done,
the router identification number is automatically the primary interface address.
Activating OSPF
To run OSPF on the router, the advanced routing image must be installed. For information on how to
install image files, see the OmniSwitch AOS Release 7 Switch Management Guide.
After the image file has been installed onto the router, you will need to load the OSPF software into
memory and enable it, as described below.
Loading the Software
To load the OSPF software into the router’s running configuration, enter the ip load ospf command at the
system prompt:
-> ip load ospf
The OPSF software is now loaded into memory, and can be enabled.
Enabling OSPF
Once the OSPF software has been loaded into the router’s running configuration (either through the CLI
or on startup), it must be enabled. To enable OSPF on a router, enter the ip ospf admin-state command at
the CLI prompt, as shown:
-> ip ospf admin-state enable
Once OSPF is enabled, you can begin to set up OSPF parameters. To disable OSPF, enter the following:
-> ip ospf admin-state disable
