Open Shortest Path First Enhancements

Software Version 2.8.1 includes the following enhancements to OSPF:

OSPF Interface Password

NSSA Translator Role

Redistributing External Routes

This section describes the enhancements. The modified commands to implement them are described in Command Reference Updates.

OSPF Interface Password

The option none has been added to the password parameter for the following commands:

add ospf interface=interface [password={nonepassword}] [other-options...]

set ospf interface=interface [password={nonepassword}] [other-options...]

This allows you to remove a previously specified password from the OSPF interface.

Command Changes

The following table summarises the modified commands:

Command

Change

 

 

add ospf interface

New none option for password parameter

 

 

set ospf interface

New none option for password parameter

 

 

NSSA Translator Role

An NSSA border router translates Type-7 LSAs into Type-5 LSAs. You can configure the NSSA translator role of an NSSA border router using the commands:

add ospf area={backbonearea-number} stubarea=nssa nssastability=1..3600 nssatranslator={candidatealways}] [other-options...]

set ospf area={backbonearea-number} stubarea=nssa nssastability=1..3600 nssatranslator={candidatealways}] [other-options...]

If you set nssatranslator to always, the NSSA router will unconditionally translate Type-7 LSAs as long as it has NSSA border router status, regardless of the translator state of other border routers in the NSSA. If it loses border router status it will stop translating Type-7 LSAs until it regains border router status.

If you set nssatranslator to candidate, the NSSA router will take part in the NSSA translator election process. The NSSA border router with the highest router identifier is elected as the translator. Once elected, the border router will translate Type-7 LSAs until it loses border router status or another NSSA border router with a higher router identifier is elected as the translator.
