None - This is the initial interface state. If you select this option from the pulldown menu on the
second screen you will be returned to the first screen and no authentication protocols will be run.
Simple - If you select 'Simple' you will be prompted to enter an authentication key. This key will
be included, in the clear, in the OSPF header of all packets sent on the network. All routers on
the network must be configured with the same key.
Encrypt - If you select 'Encrypt' you will be prompted to enter both an authentication key and an
authentication ID. Encryption uses the MD5 Message-Digest algorithm. All routers on the
network must be configured with the same key and ID.
Authentication Key - Enter the OSPF Authentication Key for the specified interface. If you do not
choose to use authentication you will not be prompted to enter a key. If you choose 'simple' or
'encrypt' the key may be up to 16 octets long. The key value will only be displayed if you are logged
on with Read/Write privileges, otherwise it will be displayed as asterisks.
Non-Configurable Data
IP Address - The IP Address of the router interface.
Link State - Indicates whether the RIP interface is up or down.
Bad Packets Received - The number of RIP response packets received by the RIP process which
were subsequently discarded for any reason.
Bad Routes Received - The number of routes, in valid RIP packets, which were ignored for any
reason (e.g. unknown address family, or invalid metric).
Updates Sent - The number of triggered RIP updates actually sent on this interface. This explicitly
does NOT include full updates sent containing new information.
Command Buttons
Configure Authentication - Display a new screen where you can select the authentication method
for the virtual link.
Submit - Send the updated configuration to the switch. Configuration changes take effect
immediately. These changes will not be retained across a power cycle unless a save is performed.
