Remarks
3. Specify an IPv6 address for
the tunnel interface.
For configuration details, see
"Configuring basic IPv6 settings."
No IPv6 address is configured for
the tunnel interface by default.
4. Configure a source address or
source interface for the tunnel
interface.
source { ip-address |
interface-type interface-number }
By default, no source address or
source interface is configured for the
tunnel interface.
The specified source address or the
primary IP address of the specified
source interface is used as the
source IP address of tunneled
packets.
5. Configure a destination
address for the tunnel
interface.
destination ip-address
By default, no destination address is
configured for the tunnel interface.
The tunnel destination address must
be the IP address of the receiving
interface on the tunnel peer. It is
used as the destination IP address of
tunneled packets.
6. (Optional.) Set the DF bit for
tunneled packets.
tunnel dfbit enable
The DF bit is not set for tunneled
packets by default.
7. Return to system view.
quit N/A
8. (Optional.) Enable dropping
of IPv6 packets using
IPv4-compatible IPv6
addresses.
tunnel discard
ipv4-compatible-packet
This feature is disabled by default.
Configuration example
Network requirements
As shown in Figure 87, configure an IPv6 over IPv4 tunnel between Switch A and Switch B so the two IPv6
networks can reach each other over the IPv4 network. Because the tunnel destination IPv4 address
cannot be automatically obtained from the destination IPv6 addresses of packets, configure an IPv6 over
IPv4 manual tunnel.
Figure 87 Network diagram
Configuration procedure
Make sure Switch A and Switch B have the corresponding VLAN interfaces created and can reach each
other through IPv4.
1. Configure Switch A:
