R3303-HP HSR6800 Routers Layer 3 - IP Services Configuration Guide

255
• The IPv6 address of the tunnel interface cannot be on the same subnet as the destination address
configured for the tunnel interface.
• The destination address of the route passing the tunnel interface cannot be on the same subnet as
the destination address configured for the tunnel interface.
• Two or more tunnel interfaces using the same encapsulation protocol must have different source and
destination addresses.
• If you specify a source interface instead of a source address for the tunnel, the source address of the
tunnel is the primary IP address of the source interface.
• Only the IPv6 over IPv6 tunnel has a maximum number of nested encapsulations for a packet.
Configuration procedure
To configure an IPv6 over IPv6 tunnel:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enable IPv6.
ipv6
By default, the IPv6 packet
forwarding function is
disabled.
3. Enter tunnel interface
view.
Interface tunnel number N/A
4. Configure an IPv6
address for the tunnel
interface.
• Configure an IPv6 global unicast address or
site-local address:
{ ipv6 address { ipv6-address prefix-length
| ipv6-address/prefix-length }
{ ipv6 address ipv6-address/prefix-length
eui-64
• Configure an IPv6 link-local address:
{ ipv6 address auto link-local
{ ipv6 address ipv6-address link-local
By default, no IPv6 address is
configured for the tunnel
interface.
5. Specify the IPv6 over
IPv6 tunnel mode.
tunnel-protocol ipv6-ipv6
The default mode is GRE. The
same tunnel mode should be
configured at both ends of the
tunnel. Otherwise, packet
delivery fails.
6. Configure a source
address or interface for
the tunnel interface.
source { ipv6-address | interface-type
interface-number }
By default, no source address
or interface is configured for
the tunnel.
7. Configure the
destination address for
the tunnel interface.
destination ipv6-address
By default, no destination
address is configured for the
tunnel.
8. Configure the
maximum number of
nested encapsulations
of a packet.
encapsulation-limit [ number ]
Optional.
4 by default.
