R3303-HP 6600/HSR6600 Routers Layer 3 - IP Routing Command Reference

135
• A so small retransmission interval will lead to unnecessary retransmissions. A big value is
appropriate for a low speed link.
• You need to specify an appropriate transmission delay with the trans-delay keyword.
• You can specify either MD5/HMAC-MD5 authentication or simple authentication for a virtual link.
For MD5/HMAC-MD5 authentication, you can configure multiple keys by executing this command
multiple times, and each command must have a unique key ID and key string.
• For security purposes, all passwords, including passwords configured in plain text, are saved in
cipher text to the configuration file.
• If no cipher or plain is specified, the default password type for MD5/HMAC-MD5 authentication
mode is cipher, and the default password for simple authentication mode for is plain.
• If you configure OSPF authentication for both the backbone area and a virtual link, the virtual link
uses the OSPF authentication configured on it.
