Configuration Example - HP 6125G Configuration Manual

Step
8. Configure the maximum
number of nested
encapsulations of a
packet.
9. Return to system view.
10. Enable dropping of IPv6
packets using
IPv4-compatible IPv6
addresses.

Configuration example

Network requirements
As shown in
IPv6 network. Configure an IPv6 over IPv6 tunnel between Switch A and Switch B to make the two
subnets reachable to each other without disclosing their IPv6 addresses to the IPv6 network.

Configuration procedure
Before configuring an IPv6 over IPv6 tunnel, make sure that Switch A and Switch B have the
corresponding VLAN interfaces created and can reach each other.
Configure Switch A:
•
# Enable IPv6.
<SwitchA> system-view
[SwitchA] ipv6
# Configure an IPv6 address for VLAN-interface 100.
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] ipv6 address 2002:1::1 64
[SwitchA-Vlan-interface100] quit
# Configure an IPv6 address for VLAN-interface 101 (the physical interface of the tunnel).
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] ipv6 address 2002::11:1 64
[SwitchA-Vlan-interface101] quit
# Create service loopback group 1 to support the tunnel service.
[SwitchA] service-loopback group 1 type tunnel
