Release Information

Statement introduced in Junos OS Release 15.1X53-D55.

Description

Configure IPv6 Router Advertisement (RA) guard on an interface. In an IPv6 deployment, RA guard protects against rogue RA messages generated either maliciously or unintentionally by unauthorized or improperly configured routers connecting to the network segment. An RA guard policy is used to validate incoming RA messages on the basis of whether they match the conditions defined in a policy.

Before you can configure RA guard on an interface, you must first configure a policy at the [edit forwarding-options access-security router-advertisement-guard] hierarchy level. The policy is then applied to an interface at the [edit forwarding-options access-security router-advertisement-guard interface interface-name] hierarchy level.

Note

If you apply an RA guard policy on an interface, you must enable RA guard on the VLAN that is associated with that interface by using the vlan statement at the [edit forwarding-options access-security router-advertisement-guard] hierarchy level.

The remaining statements are explained separately. See CLI Explorer.
