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={none|password}]

[other-options...]

set ospf interface=interface [password={none|password}]

[other-options...]

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

Command Changes

The following table summarises the modified commands:

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={backbone|area-number} stubarea=nssa

nssastability=1..3600 nssatranslator={candidate|always}]

[other-options...]

set ospf area={backbone|area-number} stubarea=nssa

nssastability=1..3600 nssatranslator={candidate|always}]

[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.
