We have a symmetricon TP5500 on our network. This GPS clock receiver is used for ipv4 clocking. Surprise that we have no ipv6 clock support.
So a ASR9K was used to sync to our ipv4 clock source, and I configured a interface with a ipv6 address for testing.

Better yet, a simple clock access-group for the peers that you want and applied for both ipv4 & ipv6 would work also.

access-group ipv6 query-only DENY_ACL
