#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Creates an IPv6 prefix list for route filtering; specifies a list entry—a permit or deny clause for a network address. The no version removes the specified prefix list or the specified list entry.

#### Options

- listName—Name of the IPv6 prefix list; a string of up to 32 characters
- desc—Description of the prefix list
- sequence—Number in the range 0–65535 that indicates the position the prefix list entry has in the already existing list of entries for the prefix list; if you do not specify a sequence, the command uses the value of the last sequence number + 5
- permit—When specified, the router redistributes any prefix that matches the filtered route based on the set actions
- deny—When specified, the router drops any prefix that matches the filtered route
- ipv6Prefix—Network route that you want to filter, in the format ipv6Address / length, where
  - ipv6Address—Base IPv6 address of the network route that you want to filter (for example, ::ffff:a:b:c:d)
  - length—Length of the network prefix; number of bits masking base address to produce address to be matched
- geNumber—Route being filtered matches if its prefix is within the range specified: greater than or equal to geNumber and less than or equal to 32
- leNumber—Route being filtered matches if its prefix is within the range specified: greater than or equal to length and less than or equal to leNumber
