Chapter 37 OSPF Table 120 IP Application > OSPF Configuration > Redistribute (continued) LABEL DESCRIPTION Summary address Enter a network IP address which can cover more than one network in 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. Subnet mask Add Cancel 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. Enter the subnet mask for this summary IP address which can cover multiple networks. Click Add to save your changes to the Switch's run-time memory. The 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 nonvolatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. 37.6 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 110 for more information). Once you create an IP routing domain, an OSPF interface entry is automatically created. See Section 37.1 on page 331 for more information on OSPF. In the OSPF Configuration screen, click Interface to display the OSPF Interface screen. Figure 166 IP Application > OSPF Configuration > OSPF Interface XGS-4526/4528F/4728F User's Guide 341
