Parameters
name
Specifies the name of the IPv6 prefix list to associate with the RA guard policy.
Modes

RA guard policy configuration mode

Usage Guidelines

This command associates an IPv6 prefix list with an RA guard policy so that only the RAs that have the given prefix are forwarded. You must provide the name of an IPv6 prefix list already configured using the ipv6 prefix-list command. For more information on configuring an IPv6 prefix list using the ipv6 prefix-list command, see the FastIron Ethernet Switch Layer 3 Routing Configuration Guide .

Only one prefix list can be associated with an RA guard policy. If the command is configured twice with different prefix lists, the latest configured prefix list is associated with the RA guard policy.

The no form of the command deletes the prefix list from the RA guard policy.

Examples

The following example associates an IPv6 prefix list with an RA guard policy: 

device(config)# ipv6 prefix-list raguard-prefix1
device(config)# ipv6 raguard policy p1
device(config-ipv6-RAG-policy p1)# prefix-list raguard-prefix1
