Configuring OSPF

OSPF Authentication

OSPF packets can be authenticated as coming from trusted routers by the use of predefined
passwords. The default for routers is to use not authentication.
There are two other authentication methods − simple password authentication (key) and

Message Digest authentication (MD-5).

Message Digest Authentication (MD-5)
MD-5 authentication is a cryptographic method. A key and a key-ID are configured on each
router. The router then uses an algorithm to generate a mathematical "message digest" that is
derived from the OSPF packet, the key and the key-ID. This message digest (a number) is
then appended to the packet. The key is not exchanged over the wire and a non-decreasing
sequence number is included to prevent replay attacks.

Simple Password Authentication

A password (or key) can be configured on a per-area basis. Routers in the same area that
participate in the routing domain must be configured with the same key. This method is
possibly vulnerable to passive attacks where a link analyzer is used to obtain the password.
Description
The name of the IP interface on which RIP is to be setup. This interface
must be previously configured on the Switch.
Toggle among Disabled, V1 Only, V1 Compatible, and V2 Only. This entry
specifies which version of the RIP protocol will be used to transmit RIP
packets. Disabled prevents the transmission of RIP packets.
Toggle among Disabled, V1 Only, V2 Only, and V1 and V2. This entry
specifies which version of the RIP protocol will be used to interpret
received RIP packets. Disabled prevents the reception of RIP packets.
A password to be used to authenticate communication between routers on
the network.
Toggle between Disabled and Enabled to specify that routers on the
network should us the Password above to authenticate router table
exchanges.
Toggle between Disable and Enable to disable or enable this RIP interface
on the switch.
