Configuring a GRE over IPv6 tunnel

Configuration restrictions and guidelines

Deleting a tunnel interface also deletes the functions configured on this tunnel interface.
•
The source address or interface and the destination address that are specified for the tunnel
•
interface must be a public address or interface.
The source address and destination address of a tunnel uniquely identify a path.
•
The source address and the destination address must be configured at both ends of the tunnel.
The source address at one end must be the destination address at the other end, and vice
versa.
The source addresses, destination addresses, or both source and destination addresses must be
•
different for the tunnel interfaces using the same encapsulation protocol.
If you configure a source interface for a tunnel interface, the tunnel interface takes the primary IP
•
address of the source interface as its source address.
When configuring a route through the tunnel, you are not allowed to set up a static route whose
•
destination address is in the subnet of the tunnel interface. Instead, you can do one of the following:
Command
tunnel-protocol gre
source { ip-address | interface-type
interface-number }
the destination
for the tunnel destination ip-address

Remarks
Optional.
The default tunnel mode is GRE
over IPv4.
You must configure the same tunnel
mode on both ends of a tunnel.
Otherwise, packet delivery may
fail.
By default, no source address or
interface is configured for a tunnel
interface.
By default, no destination address
is configured for a tunnel interface.
Each end of the tunnel must have a
route (static or dynamic) through
the tunnel to the other end.
N/A
Optional.
By default, the device does not
discard the IPv4-compatible IPv6
packets.
