You can configure an IPv6 prefix list for basic traffic filtering.
device# configure terminal
(config)# ipv6 prefix-list prefix-filter-1 permit FE80::/10 ge 25 le 25
The ge
						ge-value or le 
						
							le-value that you specify must meet the following condition
						for prefix-length: ge-value <= le-value <= 128. 
If you do not specify ge ge-value or le le-value, the prefix list matches only on the exact prefix you specify with the ipv6-prefix/prefix-length parameter.
