Displaying And Maintaining Gre - HPE FlexNetwork HSR6800 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
For more information about the interface tunnel, source, destination, and tunnel discard
ipv4-compatible-packet commands and additional configuration commands on a tunnel interface,
see tunnel configuration and commands in Layer 3—IP Services Configuration Guide and 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 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.
