Configuring An Automatic Ipv4-Compatible Ipv6 Tunnel; Configuration Example - HP FlexNetwork MSR2003 Configuration Manual

Configuring an automatic IPv4-compatible IPv6
tunnel
Follow these guidelines when you configure an automatic IPv4-compatible IPv6 tunnel:
•
You do not need to configure a destination address for an automatic IPv4-compatible IPv6
tunnel. The destination address of the tunnel is embedded in the destination IPv4-compatible
IPv6 address.
•
Do not specify the same source addresses for local tunnel interfaces in the same tunnel mode.
To configure an automatic IPv4-compatible IPv6 tunnel:
Step
1. Enter system view.
2. Enter automatic
IPv4-compatible IPv6 tunnel
interface view.
3. Specify an IPv6 address for
the tunnel interface.
4. Configure a source address
or source interface for the
tunnel interface.
5. (Optional.) Set the DF bit for
tunneled packets.
6. Return to system view.

Configuration example

Network requirements
As shown in
network. Configure an automatic IPv4-compatible IPv6 tunnel between the two routers to enable
IPv6 communications over the IPv4 network.

Configuration procedure
Make sure Router A and Router B can reach each other through IPv4.
•
Configure Router A:
# Specify an IPv4 address for GigabitEthernet 2/0/1.

Remarks
N/A
N/A
By default, no IPv6 address is
configured for the tunnel interface.
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.
By default, the DF bit is not set for
tunneled packets.
