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. |
Options
no-attrset | — | (Optional) Disables attribute set messages on the independent AS domain. |
Required Privilege Level
