Syntax

maximum-preference { high | low | medium }

no maximum-preference { high | low | medium }

The router preference setting for the RA guard policy is high (allows all RAs).

Parameters

high: Configures the router preference of RAs for the RA guard policy to high (allows all RAs). This is the default.
low: Allows RAs of low router preference.
medium: Allows RAs of low and medium router preference.

Usage Guidelines

If a very low value is set, the RAs expected to be forwarded might get dropped.

The no form of this command removes the router preference for an RA guard policy.

The following example configures the RA guard policy router preference to low:

device(config)# ipv6 raguard policy p1
device(config-ipv6-RAG-policy p1)# maximum-preference low
