Configuring An Ipv6 Over Ipv6 Tunnel - HPE FlexNetwork HSR6800 Configuration Manual

Configuring an IPv6 over IPv6 tunnel

Follow these guidelines when you configure an IPv6 over IPv6 tunnel:
•
The tunnel destination address specified on the local device must be identical with the tunnel
source address specified on the tunnel peer device.
•
Do not specify the same source and destination addresses for local tunnel interfaces in the
same tunnel mode.
•
The IPv6 address of the tunnel interface cannot be on the same subnet as the destination
address configured for the tunnel interface.
•
To ensure correct packet forwarding, identify whether the destination IPv6 network and the IPv6
address of the local tunnel interface are on the same subnet. If they are not, configure a route
reaching the destination IPv6 network through the tunnel interface. You can configure the route
by using one of the following methods:
Configure a static route, and specify the local tunnel interface as the egress interface or
specify the IPv6 address of the peer tunnel interface as the next hop.
Enable a dynamic routing protocol on both tunnel interfaces to achieve the same purpose.
For more information about route configuration, see Layer 3—IP Routing Configuration Guide.
•
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.
To configure an IPv6 over IPv6 tunnel:
Step
1. Enter system view.
2. Enter IPv6 over IPv6 tunnel
interface view.
3. Configure an IPv6 address
for the tunnel interface.
4. Configure the source address
or source interface for the
tunnel interface.
5. Configure the destination
address for the tunnel
interface.
6. (Optional.) Set the maximum
number of nested
encapsulations of a packet.

Remarks
N/A
N/A
By default, no IPv6 address is
configured for the tunnel
interface.
By default, no source address or
interface is configured for the
tunnel.
If you specify a source address,
it is used as the source IPv6
address of tunneled packets.
If you specify a source interface,
the lowest IPv6 address of this
interface is used as the source
IPv6 address of tunneled
packets.
By default, no destination
address is configured for the
tunnel.
The tunnel destination address
must be the IPv6 address of the
receiving interface on the tunnel
peer. It is used as the destination
IPv6 address of tunneled
packets.
By default, there is no limit to the
nested encapsulations of a
packet.
