configure ospfv3 area nssa

configure ospfv3 area area-identifier nssa [nosummary | summary] stub-default-cost cost {translate}

Description

NSSAs are similar to the OSPFv3 stub area configuration option, but have the following two additional capabilities:

External routes originating from an ASBR connected to the NSSA can be advertised within the NSSA.
External routes originating within the NSSA can be propagated to other areas if translated to AS-external LSAs. When configuring an OSPFv3 area as an NSSA, the translate option should only be used on NSSA border routers, where translation is to be enforced. If translate is not used on any NSSA border router, one of the ABRs for that NSSA is elected to perform translation.


`area-identifier`	Area identifier.
nosummary	Inter-Area-Prefix LSAs prohibited.
summary	Inter-Area-Prefix LSAs allowed.
`cost`	Route metric.
translate	Always translate NSSA LSAs to AS-external LSAs.

None.

This command must specify the cost of the default route advertised into the NSSA.

This command was first available in ExtremeXOS 21.1.

This command is available on all ExtremeSwitching Universal switches.
