R3303-HP HSR6800 Routers Layer 3 - IP Routing Command Reference

177
Usage guidelines
Whether a password should use ip or osi is not affected by the actual network environment.
The password in the specified mode is inserted into all outgoing hello packets and is used for
authenticating the incoming hello packets. Only the authentication succeeds can the neighbor
relationship be formed.
For two routers to become neighbors, the same authentication mode and password must be specified at
both ends.
For security purposes, all passwords, including passwords configured in plain text, are saved in cipher
text to the configuration file.
If you configure a password without specifying a level, the password applies to both Level-1 and Level-2.
If neither ip nor osi is specified, the OSI related fields in LSPs are checked.
The level-1 and level-2 keywords are available only on Layer 3 Ethernet interfaces.
The level-1 and level-2 keywords are configurable on an interface that has had IS-IS enabled with the isis
enable command.
Examples
# On GigabitEthernet 4/0/1, configure the Level-1 adjacency authentication mode as simple, and set
the plaintext password to 123 456 .
