Configuring An Automatic Ipv4-Compatible Ipv6 Tunnel - H3C MSR 2600 Configuration Manual

# Router B and Router A can ping the IPv6 address of Ethernet 1/1 of each other. For example, ping the
IPv6 address of Ethernet 1/1 on Router B from Router A.
[RouterA] ping ipv6 3003::1
Ping6(56 data bytes) 3001::1 --> 3003::1, press escape sequence to break
56 bytes from 3003::1, icmp_seq=0 hlim=64 time=45.000 ms

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,
•
because the destination address of the tunnel is embedded in the destination IPv4-compatible IPv6
address of packets.
The source addresses of local tunnels of the same tunnel mode cannot be the same.
•
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.

Remarks
N/A
N/A
No IPv6 address is configured for the
tunnel interface by default.
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.
The DF bit is not set for tunneled
packets by default.
