ONFIGURATION
When you configure a static route, you need to configure a route to the
■
destination address (the destination IP address of the packet, instead of the
IPv4 address of the tunnel destination) and set the next-hop to the tunnel
interface number or network address at the local end of the tunnel. Such a
route must be configured at both ends of the tunnel.
Before referencing a link aggregation group on the tunnel interface to receive
■
and send packets, make sure that the aggregation group has been configured.
Otherwise, the tunnel interface will not be up to communicate.
Network requirements
Isolated IPv6 networks are interconnected through a 6to4 tunnel over the IPv4
network.
