link-local
By default, no IPv6 address is
configured for the tunnel interface.
Specify the IPv6 over IPv6 tunnel
mode
tunnel-protocol ipv6-ipv6
Optional
The default tunnel mode is GRE over
IPv4.
The same tunnel mode should be
configured at both ends of the tunnel.
Otherwise, packet delivery will fail.
Configure a source address or
interface for the tunnel interface source { ipv6-address |
interface-type interface-number }
Required
By default, no source address or
interface is configured for the tunnel.
Configure the destination
address for the tunnel interface destination ipv6-address
Required
By default, no destination address is
configured for the tunnel.
Configure the maximum number
of nested encapsulations of a
packet

[ number ] Optional
4 by default.
NOTE:
•
To encapsulate and forward IPv6 packets whose destination address does not belong to the subnet
where the receiving tunnel interface resides, you need to 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 needs to be performed 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
IPv6 Static Routing Configuration or other routing protocol configurations in
the IP Routing Volume.
• The IPv6 address of a tunnel interface must not be on the same subnet as the destination address of the
tunnel.
• The destination address of a route with the tunnel interface as the egress interface must not be on the
same subnet as the destination address of the tunnel.
• Two or more tunnel interfaces using the same encapsulation protocol must have different source and
destination addresses.
• If you specify a source interface instead of a source address for the tunnel, the source address of the
tunnel is the primary IP address of the source interface.
• Only the IPv6 over IPv6 tunnel has a maximum number of nested encapsulations for a packet.
