prefix-list
RA guard policy configuration mode
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.
