MD5 Key

The MD5 Key Table Configuration menu 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 Interface Configuration menu below.
To configure an MD5 Key, click the MD5 Key link to open the following dialog box:

Route Redistribution Settings

Route redistribution allows routers on the network − that 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 DES-6500 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.

Description
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.
