Configuration Example - H3C MSR 2600 Configuration Manual

Step
4. Configure a source address or
source interface for the tunnel
interface.
5. Configure a destination
address for the tunnel
interface.
6. (Optional.) Set the DF bit for
tunneled packets.
7. Return to system view.
8. (Optional.) Enable dropping
of IPv6 packets using
IPv4-compatible IPv6
addresses.

Configuration example

Network requirements
As shown in
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.

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

Remarks
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, 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.
The DF bit is not set for tunneled
packets by default.
N/A
This feature is disabled by default.
