If one is given a giant /64 block in the lab and asks candidate to subnet it
as needed, whatz the best approach to assign IPv6 addresses and mask so that
they are easily aggregatable ?
For eg: Lab would consist of all these links.
1) Point-to-Point FR links (use /126 mask ?)
2) Point-to-Multipoint FR links (use /125 mask ? assuming < 8 routers)
3) Ethernet links (??)
4) GRE Links (/126 mask ?)
5) IPv6 Tunnels (??)
On the other hand, if the IPv6 Network prefix is not provided, what scope is
best recommended (Global unicast, site-local, etc) ?
Thnx,
Naveen.
