Description

Configure IPv6 Router Advertisement (RA) guard on a VLAN. 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 a VLAN, you must first configure a policy at the [edit forwarding-options access-security router-advertisement-guard] hierarchy level. The policy is then applied to the VLAN at the [edit forwarding-options access-security router-advertisement-guard vlans vlan-name] hierarchy level.

The remaining statements are explained separately. See CLI Explorer.
