Such an interface can serve as the source interface of thetunnel to ensure that the tunnel destination address is reachable.Configuration Procedure Follow these steps to configure a 6to4 tunnel:To do… Use the command… RemarksEnter system view system-view -Enable IPv6 ipv6 RequiredBy default, the IPv6 packetforwarding function isdisabled.
