Displaying And Maintaining Gre - HP FlexNetwork MSR2003 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
checksum.
7. (Optional.) Configure a GRE
key for the tunnel interface.
8. Return to system view.
9. (Optional.) Configure the
device to discard IPv6
packets with IPv4-compatible
IPv6 addresses

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 checksum is disabled.
By default, no GRE key is configured for a
GRE tunnel interface.
The two ends of a GRE tunnel must have
the same key or both have no key.
N/A
By default, the device does not discard
such IPv6 packets.
