xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch MD5 Key Settings This window allows the entry of a 16-character Message Digest − version 5 (MD5) key that can be used to authenticate every packet exchanged between OSPF routers. It is used as a security mechanism to limit the exchange of network topology information to the OSPF routing domain. MD5 Keys created here can be used in the OSPF windows below. To configure an MD5 Key, click L3 Features > MD5 Key Settings, as shown below: The following fields can be set: Parameter Description Figure 4- 9. MD5 Key Settings window Key ID (1-255) Key A number from 1 to 255 used to identify the MD5 Key. A alphanumeric string of between 1 and 16 case-sensitive characters used to generate the Message Digest which is in turn, used to authenticate OSPF packets within the OSPF routing domain. Click Add/Modify to enter the new Key ID settings. To delete a Key ID entry, click the corresponding under the Delete heading. Route Redistribution Settings Route redistribution allows routers on the network, which are running different routing protocols to exchange routing information. This is accomplished by comparing the routes stored in the various routers' routing tables and assigning appropriate metrics. This information is then exchanged among the various routers according to the individual router's current routing protocol. The Switch can redistribute routing information among OSPF, RIP, and BGP routing protocols to all routers on the network that are running OSPF, RIP, and BGP. Routing information entered into the Static Routing Table on the local Switch is also redistributed. Entering the metric 0 specifies transparency. This window will redistribute routing information among the OSPF, RIP, and BGP routing protocols to all routers on the network that are running OSPF, RIP, and BGP. To access the Route Redistribution Settings window, click L3 Features > Route Redistribution Settings, as shown below: Figure 4- 10. Route Redistribution Settings window 179
