M4300 Intelligent Edge Series Fully Managed Stackable Switches Table 139. OSPF Virtual Link Configuration (continued) Field State Metric Description The state of the interface. It takes one the following values: • Down. This is the initial interface state. The lower-level protocols indicated that the interface is unusable. Interface parameters are set to their initial values. All interface timers are disabled, and there are no adjacencies associated with the interface. • Waiting. The router is trying to determine the identity of the backup designated router by monitoring received hello packets. The router is not allowed to elect a backup designated router or a designated router until it transitions out of waiting state. This prevents unnecessary changes of backup designated router. • Point-to-Point. The interface is operational, and is connected either to the virtual link. On entering this state the router attempts to form an adjacency with the neighboring router. hello packets are sent to the neighbor every hello interval seconds. • Designated Router. This router is the designated router on the attached network. Adjacencies are established to all other routers attached to the network. The router must also originate a network-LSA for the network node. The networkLSA contain links to all routers (including the designated router) attached to the network. • Backup Designated Router. This router is the backup designated router on the attached network. It is promoted to designated router if the present designated router fails. The router establishes adjacencies to all other routers attached to the network. The backup designated router performs slightly different functions during the flooding procedure, as compared to the designated router. • Other Designated Router. The interface is connected to a broadcast or NBMA network on which other routers were selected to be the designated router and backup designated router either. The router attempts to form adjacencies to both the designated router and the backup designated router. The metric value used by the Virtual Link. Configure the OSPF Route Redistribution You can configure the OSPF Route Redistribution parameters. The allowable values for each field are displayed next to the field. If any invalid values are entered, an alert message is displayed with the list of all the valid values. Configure the OSPF route redistribution: 1. Launch a web browser. 2. In the address field of your web browser, enter the IP address of the switch. The login window opens. 3. Enter admin as the user name, enter your local device password, and click the Login button. The first time that you log in, no password is required. However, you then must specify a local device password to use each subsequent time that you log in. The System Information page displays.
