HOWTO Make an IPv6 Filter

All filter evaluation defaults to:

afi ipv4.unicast

If no address family identifier (afi) is mentioned.

You can use something like this however:

RtConfig> @RtConfig access_list filter afi ipv6 AS1741
!

no ipv6 access-list ipv6-100
ipv6 access-list ipv6-100 permit 2001:708::/32 any
ipv6 access-list ipv6-100 deny any any

Note that RtConfig expects hex digits A-F to be in upper case, and will report a syntax error if it's presented with IPv6 addresses with any lower-case hex digits.
