Hi Group,
Does anyone have a good explanation for "area nssa translate"? Frome
the DocCD:
area nssa translate
To configure an area as a not-so-stubby area (NSSA) and configure the Open
Shortest Path First (OSPF) Forwarding Address Suppression in Translated
Type-5 LSAs feature, use the *area nssa translate *command in router
configuration mode. To remove the NSSA distinction from the area, use the *
no* form of this command.
*area* *area-id* *nssa* *translate type7 suppress-fa *
no *area* *area-id* *nssa* *translate type7 suppress-fa *
Syntax Description
*area-id*
Identifier of the area for which authentication is to be enabled. The
identifier can be specified as either a decimal value or an IP address.
*translate*
Translates one type of LSA to another type of LSA. This keyword takes effect
only on an NSSA area border router (ABR) or NSSA Autonomous System Boundary
Router (ASBR).
*type7*
Translates a Type-7 LSA to a Type-5 LSA. This keyword takes effect only on
an NSSA ABR or an NSSA ASBR.
*suppress-fa*
Suppresses the forwarding address of the Type-7 LSAs from being placed in
the Type-5 LSAs. This keyword takes effect only on an NSSA ABR or an NSSA
ASBR.
Doesn't an NSSA ABR do this by it's very nature? Also, could someone clarify
when you might use forward address supression?
Thanks,
Chris
