Configuring an IPv6 over IPv6 tunnel
Configuration prerequisites
Configure IP addresses for interfaces (such as the VLAN interface, and loopback interface) on the device
to ensure normal communication. One of the interfaces will be used as the source interface of the tunnel.
Configuration guidelines
Follow these guidelines when you configure an IPv6 over IPv6 tunnel:
•
Specify public addresses or interfaces as the source and destination addresses or interfaces.
•
To encapsulate and forward IPv6 packets whose destination address does not belong to the subnet
where the receiving tunnel interface resides, configure a static route or dynamic routing for
forwarding those packets through this tunnel interface. If you configure a static route to that
destination IPv6 address, specify this tunnel interface as the outbound interface, or the peer tunnel
interface address as the next hop. A similar configuration is required at the other tunnel end. If you
configure dynamic routing at both ends, enable the dynamic routing protocol on both tunnel
interfaces. For the detailed configuration, see
Layer 3—IP Routing Configuration Guide
