    That is, you can choose your own address but the high-order byte must
    be 0x5f and you must conform to the RFC 1897 format.

    Here is an example from 6bone-router.cisco.com. There is an ethernet and
    fddi ring running IPv6:

6bone-router>sh ipv route con
IPv6 Routing Table - 26 entries
Codes: C - Connected, L - Local, S - Static
Timers: Uptime/Expires

C 5F00:6D00:C01F:0700/80 [0/0]
  via 5F00:6D00:C01F:0700::0060:3E11:6772, Fddi0, 2d02h/never
C 5F00:6D00:C01F:0700:0001/80 [0/0]
  via 5F00:6D00:C01F:0700:0001:0060:3E11:6770, Ethernet0, 2d02h/never

    The next-hop (after via) is the router's IPv6 address on the respective
    interface. We use a /80 for those interfaces.
