User Guidelines
Use this command to attach an RA Guard policy to a port.
Each time the command is used, it overrides the previous command within the
same policy.
If a policy specified by the
policy-name argument is not defined, the command is
rejected.
Multiple policies with the vlan keyword can be attached to the same port if they
do not have common VLANs.
The set of rules that is applied to an input packet is built in the following way:
• The rules, configured in the policy attached to the port on the VLAN on
which the packet arrived are added to the set.
• The rules, configured in the policy attached to the VLAN are added to the
set if they have not been added.
• The global rules are added to the set if they have not been added.
Use the no ipv6 nd raguard attach-policy command to detach all user-defined
policies attached to the port.
Use the no ipv6 nd raguard attach-policy
policy-name command to detach the
specific policy from the port.
Examples

Example 2—In the following example, the RA Guard policy policy1 is attached to
