Description

Enable the router to process only the autodiscovery network layer reachability information (NLRI) update messages for VPWS and LDP-based Layer 2 VPN and VPLS update messages (BGP_L2VPN_AD_NLRI) (FEC 129).

Specifically, the auto-discovery-only statement notifies the routing process (rpd) to expect autodiscovery-related NLRI messages so that information can be deciphered and used by LDP, VPLS, and VPWS.

The auto-discovery-only statement must be configured on all provider edge (PE) routers in a VPLS or in a VPWS. If you configure route reflection, the auto-discovery-only statement is also required on provider (P) routers that act as the route reflector in supporting FEC 129-related updates.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 10.4R2.
