HP GbE2c - Blc Layer 2/3 Fiber SFP Option Application Guide

OSPF 116
OSPF features not supported in this release
The following OSPF features are not supported in this release:
• Summarizing external routes
• Filtering OSPF routes
• Using OSPF to forward multicast routes
• Configuring OSPF on non-broadcast multi-access networks (such as frame relay, X.25, and ATM)
OSPF configuration examples
A summary of the basic steps for configuring OSPF on the GbE2c is listed here. Detailed instructions for each of the
steps is covered in the following sections:
• Configure IP interfaces.
One IP interface is required for each desired network (range of IP addresses) being assigned to an OSPF area
on the switch.
• (Optional) Configure the router ID.
The router ID is required only when configuring virtual links on the switch.
• Enable OSPF on the switch.
• Define the OSPF areas.
• Configure OSPF interface parameters.
IP interfaces are used for attaching networks to the various areas.
• (Optional) Configure route summarization between OSPF areas.
• (Optional) Configure virtual links.
• (Optional) Configure host routes.
Example 1: Simple OSPF domain (CLI example)
In this example, two OSPF areas are defined—one area is the backbone and the other is a stub area. A stub area
does not allow advertisements of external routes, thus reducing the size of the database. Instead, a default summary
route of IP address 0.0.0.0 is automatically inserted into the stub area. Any traffic for IP address destinations outside
the stub area will be forwarded to the stub area’s IP interface, and then into the backbone.
Figure 21 Simple OSPF domain
Follow this procedure to configure OSPF support as shown in the figure.
1. Configure IP interfaces on each network that will be attached to OSPF areas.
In this example, two IP interfaces are needed: one for the backbone network on 10.10.7.0/24 and one for the
stub area network on 10.10.12.0/24.
>> # /cfg/l3/if 1 (Select menu for IP interface 1)
>> IP Interface 1 # addr 10.10.7.1(Set IP address on backbone network)
>> IP Interface 1 # mask 255.255.255.0(Set IP mask on backbone network)
>> IP Interface 1 # enable(Enable IP interface 1)
>> IP Interface 1 # ../if 2(Select menu for IP interface 2)
>> IP Interface 2 # addr 10.10.12.1(Set IP address on stub area network)
>> IP Interface 2 # mask 255.255.255.0(Set IP mask on stub area network)
>> IP Interface 2 # enable(Enable IP interface 2)
2. Enable OSPF.
>> IP Interface 2 # /cfg/l3/ospf/on(Enable OSPF on the switch)
