I'm looking for a way to do reverse path filtering for IPv6 in RouterOS.
I request a dynamic pool via DHCPv6-PD on my WAN interface and use it to deploy separate /64 prefixes on local vlan interfaces. As far as I can tell, the only way to implement something like rp_filter for IPv6 would be a script which inserts and updates the dynamic prefixes into an address-list for use in the IPv6 firewall.
Has anyone managed to successfully implement something like this? Is there a better way to do it?
