Filtering IPv4

Is it possible to filter out all IPv4 traffic to completely isolate a device such that onlyIPv6 traffic is allowed?  The goal is to prevent any IPv4 traffic from flowing through a device.  If this can be done, can it be configured on a router and switch or just one or the other?  Has anyone configured this?

Sorry this is a very old

Sorry this is a very old thread, but yes thats very easy when writing access-list use this:

 

any , any4 , and any6 —

any specifies both IPv4 and IPv6 traffic; 

any4 specifies only IPv4 traffic; and

any6 specifies any IPv6 traffic.
