Hi,
For ipv4 you have the following option in route-map:
set policy route-map test rule 10 match ip nexthop
-access-list
-prefix-list
For ipv6, you only have this:
set policy route-map test rule 10 match ipv6 nexthop
-ipv6 address
possible completion is only ipv6 address no access-list or prefix-list
This apply for all 1.3 or 1.4 versions
