ipv6 nd suppress-ra

Syntax

[ no ] ipv6 nd suppress-ra

Release Information

Command introduced before JunosE Release 7.1.0.
Profile Configuration mode added in JunosE Release 9.0.0.

Description

Suppresses IPv6 router advertisement transmissions on a local area network (Ethernet) interface. By default, the router automatically sends IPv6 router advertisements and solicitation messages on LAN (Ethernet) interfaces. On such interfaces, you can suppress the sending of router advertisements using this command. This command is useful for only Ethernet interfaces if you want to suppress the sending of router advertisements.

However, for interfaces other than Ethernet interfaces, you must explicitly enable IPv6 router advertisements to be sent by using the ipv6 nd command. If you disable Neighbor Discovery process by using the no ipv6 nd command on any interface type, and if you enter the no ipv6 nd suppress-ra command, the ipv6 nd command takes precedence over the ipv6 nd suppress-ra command. In such cases, although router advertisements are enabled to be sent, because Neighbor Discovery is disabled, router advertisements are not used to assign prefixes

The no version reenables the sending of IPv6 router advertisement transmissions on the LAN (Ethernet) interface.
