Dual-homed connectivity provides connectivity to the internet through two separate internet service providers (ISPs), reducing the risk of an outage due to single point of failure if one ISP fails. The ipv6 traffic-filter command is used to apply an IPv6 access list called MY-LIST to check inbound packets on an interface. NAT64 is the protocol that provides IPv4 internet connectivity to IPv6 devices.
