Displaying And Maintaining Gre - HP 5920 Series Configuration Manual

Step
4. Configure a source IPv6
address or source interface for
the tunnel interface.
5. Configure a destination IPv6
address for the tunnel
interface.
6. (Optional.) Enable GRE
keepalive and set the
keepalive interval and the
keepalive number.
7. Return to system view.
8. (Optional.) Configure the
device to discard IPv6 packets
with IPv4-compatible IPv6
addresses
For information about tunnel interfaces and more configuration commands on a tunnel interface, see
"Configuring
For more information about the interface tunnel, source, destination, and tunnel discard
ipv4-compatible-packet commands, see Layer 3—IP Services Command Reference.

Remarks
By default, no source IPv6 address
or interface is configured for a
tunnel interface.
If you configure a source IPv6
address for a tunnel interface, the
tunnel interface uses the source
IPv6 address as the source IPv6
address of the encapsulated
packets.
If you configure a source interface
for a tunnel interface, the tunnel
interface uses the IPv6 address of
the source interface as the source
IPv6 address of the encapsulated
packets.
By default, no destination IPv6
address is configured for a tunnel
interface.
The destination IPv6 address is the
IPv6 address of the physical
interface that the tunnel remote
end uses to receive packets from
the GRE tunnel.
The tunnel local end uses this
address as the destination IPv6
address of the encapsulated
packets.
By default, GRE keepalive is
disabled.
N/A
By default, the device does not
discard such IPv6 packets.
