xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch OSPF The Switch supports Open Shortest Path First (OSPF), a dynamic routing protocol used in Internet Protocol (IP) networks. OSPF Global Settings This window allows OSPF to be enabled or disabled on the Switch − without changing the Switch's OSPF configuration. To enable OSPF, first supply an OSPF Router ID (see below), select Enabled from the State drop-down menu and click the Apply button. To view the following window, click L3 Features > OSPF > OSPF > OSPF Global Settings, as shown below: Figure 4- 52. OSPF Global Settings window The following parameters are used for general OSPF configuration: Parameter Description OSPF Router ID A 32-bit number (in the same format as an IP address − xxx.xxx.xxx.xxx) that uniquely identifies the Switch in the OSPF domain. It is common to assign the highest IP address assigned to the Switch (router). If 0.0.0.0 is entered, the highest IP address assigned to the Switch will become the OSPF Router ID. If an active loopback interface exists on the device and the OSPF's router ID is auto-select, the active loopback interface's IP address will be preferred to use as router ID. If there are several active loopback interfaces, it will choose the largest IP address from all the active loopback interfaces as router ID. If there is no loopback interface, the highest IP address assigned to the Switch will become the OSPF Router ID. Current Router ID Displays the OSPF Router ID currently in use by the Switch. This Router ID is displayed as a convenience to the user when changing the Switch's OSPF Router ID. State Allows OSPF to be enabled or disabled globally on the Switch without changing the OSPF configuration. 216
