Chapter 33 OSPF
Table 100 IP Application > OSPF Configuration > Redistribute (continued)
LABEL | DESCRIPTION |
Type | Select 1 for routing protocols (such as RIP) whose external metrics are |
| directly comparable to the internal OSPF cost. When selecting a path, the |
| internal OSPF cost is added to the AB boundary router to the external |
| metrics. |
| Select 2 for routing protocols whose external metrics are not comparable |
| to the OSPF cost. In this case, the external cost of the AB boundary router |
| is used in path decision to a destination. |
|
|
Metric Value | Enter a route cost (between 0 and 16777214). The default metric value is |
| 15. |

Apply | Click Apply to save your changes to the Switch’s |
| Switch loses these changes if it is turned off or loses power, so use the |
| Save link on the top navigation panel to save your changes to the non- |
| volatile memory when you are done configuring. |
|
|
Cancel | Click Cancel to begin configuring this screen afresh. |
|
|
Summary | Enter a network IP address which can cover more than one network in |
address | order to reduce the routing table size. For example, you can use |
| 192.168.8.0/22 instead of using 192.168.8.0/24, 192.168.9.0/24, |
| 192.168.10.0/24, and 192.168.11.0/24. |
| The third octet of these four network IP addresses is 00001000, 00001001, |
| 00001010, 00001011 respectively. The first 6 digits (000010) are the |
| common part among these IP addresses. So 192.168.8.0/22 can represent |
| all of these networks. |
|
|
Subnet | Enter the subnet mask for this summary IP address which can cover |
mask | multiple networks. |
|
|
Add | Click Add to save your changes to the Switch’s |
| Switch loses these changes if it is turned off or loses power, so use the |
| Save link on the top navigation panel to save your changes to the non- |
| volatile memory when you are done configuring. |

Cancel | Click Cancel to begin configuring this screen afresh. |

33.6 Configuring OSPF Interfaces
To configure an OSPF interface, first create an IP routing domain in the IP Setup screen (see Section 8.6 on page 86 for more information). Once you create an IP routing domain, an OSPF interface entry is automatically created. See Section 33.1 on page 277 for more information on OSPF.
