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.
5. Configure a destination IPv6
address for the tunnel
interface.
destination ipv6-address

address is configured for a tunnel
interface.
The destination IPv6 address is the

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.
