LAC for IPv6 address family and firewalls

You can configure the LAC to create the IPv6 address family (inet6) when tunneling the subscriber to the LNS. By default, the LAC requires only family inet to enable forwarding into an IP tunnel. It can apply IPv4 firewall filters to the session. Even when family inet6 is included in the dynamic profile, by default it is not created and IPv6 firewall filters cannot be applied. Include the enable-ipv6-services-for-lac statement at the [edit services l2tp] hierarchy level to allow the IPv6 family to be created and IPv6 filters to be applied. Use the show services l2tp summary command to display the current state, Disabled or Enabled, in the IPv6 Ssrvices for LAC sessions field.
