Junos OS extends IPsec support on MS-MICs and MS-MPCs to IPv6 traffic. IPsec support on MS-MICs and MS-MPCs is limited to the ESP protocol, and now enables you to configure IPv4 and IPv6 tunnels that can carry IPv6 as well as IPv4 traffic. To enable IPv6 traffic over an IPsec tunnel, configure an IPv6 address for the local-gateway statement under the [edit services service-set service-set-name ipsec-vpn-options] hierarchy level.
