Step Command Remarks
5. Configure the destination
address for the tunnel
interface.
destination ipv6-address
By default, no destination
address is configured for the
tunnel.
The tunnel destination address
must be the IPv6 address of the
receiving interface on the tunnel
peer. It is used as the destination
IPv6 address of tunneled packets.
6. (Optional.) Configure the
maximum number of nested
encapsulations of a packet.
encapsulation-limit number
By default, there is no limit to the
nested encapsulations of a
packet.
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
The default setting is disabled.
Configuration example
Network requirements
As shown in Figure 110, configure an IPv6 over IPv6 tunnel between Router A and Router B so the two
IPv6 networks can reach each other without disclosing their IPv6 addresses.
Figure 110 Network diagram
Configuration procedure
Make sure Router A and Router B can reach each other through IPv6.
• Configure Router A:
# Specify an IPv6 address for Ethernet 1/1.
<RouterA> system-view
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] ipv6 address 2002:1::1 64
[RouterA-Ethernet1/1] quit
# Specify an IPv6 address for Serial 2/0, which is the physical interface of the tunnel.
[RouterA] interface serial 2/0
[RouterA-Serial2/0] ipv6 address 2001::11:1 64
[RouterA-Serial2/0] quit
