Release Information Statement introduced before Junos OS Release 7.4.
no-attrset option introduced in Junos OS Release 10.4.
Description Configure an independent AS domain.
The independent domain uses transitive path attribute 128 (attribute set) messages to
tunnel the independent domain’s BGP attributes through the internal BGP (IBGP) core.
This improves the transparency of Layer 3 VPN services for customer networks by
preventing the IBGP routes that originate within an autonomous system (AS) in the
customer network from being sent to a service provider’s AS. Similarly, IBGP routes that
originate within an AS in the service provider’s network are prevented from being sent to
a customer AS.
NOTE: In Junos OS Release 10.3 and later, if BGP receives attribute 128 and
you have not configured an independent domain in any routing instance, BGP
treats the received attribute 128 as an unknown attribute.
NOTE: The [edit logical-systems] hierarchy level is not applicable in ACX
Series routers.
Options no-attrset—(Optional) Disables attribute set messages on the independent AS domain.
