n
For the configuration of the tunnel interface MTU, refer to the ipv6 mtu
command in the Switch 8800 Command Reference Guide.

CAUTION:
■ For automatic IPv4-compatible IPv6 tunnels, 6to4 tunnels, or ISATAP tunnels,
their tunnel interfaces must have different source addresses.
■ Two or more tunnel interfaces using the same encapsulation protocol must
have different source and destination addresses.
Create a tunnel interface and enter
tunnel interface view
interface tunnel number Required
By default, there is no
tunnel interface on the
device.
Configure an IPv6
address for the
tunnel interface
Configure an IPv6
global unicast
address or
site-local address
ipv6 address {
ipv6-address prefix-length
|
ipv6-address/prefix-lengt
h }
Required.
Use either command.
By default, no IPv6 global
unicast address or
site-local address is
configured for the tunnel
interface.
ipv6 address
ipv6-address/prefix-length
eui-64
Configure an IPv6
link-local address
ipv6 address auto
link-local
Optional
By default, a link-local
address will automatically
be generated when an
IPv6 global unicast
address or site-local
address is configured.
ipv6 address
ipv6-address link-local
Set a 6to4 tunnel tunnel-protocol
ipv6-ipv4 6to4
Required
By default, the tunnel is a
GRE tunnel. The same
tunnel type should be
configured at both ends
of the tunnel. Otherwise,
packet delivery will fail.
Configure a source address for the
tunnel
source { ip-address |
ipv6-address |
interface-type
interface-number }
Required
By default, no source
address or interface is
configured for the tunnel.
Configure a link aggregation group ID
to be referenced by the tunnel
interface
aggregation-group
aggregation-group-id
Required
Enable the expedite termination
function
expediting enable Optional
By default, the expedite
termination function is
disabled.
Configure an address and mask for
the expedite termination subnet
expediting subnet
ip-address mask
Optional
By default, no expedite
termination subnet is
configured for a tunnel.
