xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch User Manual MD5 Key Table Configuration The MD5 Key Table Configuration menu allows the entry of a sixteen character Message Digest − version 5 (MD5) key which 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 menu below. To configure an MD5 Key, click the MD5 Key link to open the following dialog box: Figure 6- 115. MD5 Key Setting and Table window The following fields can be set: Parameter Key ID Description A number from 1 to 255 used to identify the MD5 Key. 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 Apply to enter the new Key ID settings. To delete a Key ID entry, click the corresponding heading. Route Redistribution Settings under the Delete 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 routers current routing protocol. The Switch can redistribute routing information between the OSPF and RIP routing protocols to all routers on the network that are running OSPF or RIP. Routing information entered into the Static Routing Table on the local xStack switch is also redistributed. Routing information source − OSPF and the Static Route table. Routing information will be redistributed to RIP. The following table lists the allowed values for the routing metrics and the types (or forms) of the routing information that will be redistributed. Route Source Metric Type OSPF 0 to 16 All Internal External ExtType1 ExtType2 Inter-E1 Inter-E2 RIP 0 to 16777214 Type 1 Type 2 Static 0 to 16777214 Type 1 Type 2 Local 0 to 16777214 Type 1 Type 2 Table 6- 6.
