IPv6 transit network

[JKnott]

I was just looking at my tunnel addresses and noticed there are 2 transit networks, 1 link local /64 and 1 with a /64 address I configured in the IPv6 Tunnel Network box. Are both necessary? Shouldn't the link local be sufficient?

To clarify, the 2 ends need addresses, but it's not necessary to have 2 /64 networks to connect them. For example, my cable modem has a /64 link local network, but a /128 host address. So, a link local network and a /128 address or just a /64 specified address network could be used.
