GRE was originally designed as multiprotocol encapsulation. Therefore, it
can carry IPv6, IPv4, IPX (you name it) etc on the same tunnel, e.g.
interface Tunnel0
ip address 23.23.23.3 255.255.255.0
ipv6 address 2001::3/64
ipx network 100
tunnel source Loopback0
tunnel destination 150.1.2.2
On contrary, 6in4 tunnels are exclusively for IPv6 - they have the smallest
overhead possible, and based on that factor are more efficient for IPv6
tunneling than "generic" GRE tunnels.
