5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide permit deny ipv6-prefix/prefix-length ge length le length renumber-interval firststatement-number with the same sequence number. The value ranges from 1 to 4,294,967,294. Permit routes whose destination prefix matches the statement. Deny routes whose destination prefix matches the statement. Specifies the match criteria for routes being compared to the prefix list statement. The ipv6- prefix can be any valid IP prefix. The length is any IPv6 prefix length from 0 to 32. (Optional) If this option is configured, then a prefix is only considered a match if its network mask length is greater than or equal to this value. This value must be longer than the network length and less than or equal to 32. (Optional) If this option is configured, then a prefix is only considered a match if its network mask length is less than or equal to this value. This value must be longer than the ge length and less than or equal to 32. (Optional) Provides the option to renumber the sequence numbers of the IP prefix list statements with a given interval starting from a particular sequence number. The valid range for renumber-interval is 1100, and the valid range for first-statement-number is 1-1000. Default The default is Prefix lists are not configured. When neither the le nor the ge option is configured, the destination prefix must match the network/length. If the ge option is configured but the le option is not, then any prefix with a network mask value greater than or equal to the ge value is considered a match. Similarly, if the le option is configured but the ge option is not, then any prefix with a network mask value less than or equal to the le value is considered a match. Command Mode Global Config 8-34 ipv6 unreachables Enables the generation of ICMPv6 Destination Unreachable messages on a single interface or a range of interfaces. The generation of such messages is enabled by default. The no command prevents the generation of ICMPv6 Destination Unreachable messages. ipv6 unreachables no ipv6 unreachables Parameters None Default The default is Enabled. 823
