| Can a single global address (say 2222::1111) be configured on multiple
| interfaces of a single ip6 node.
Depends what the implementation allows, but I doubt many would permit
that - the address (with the prefix length) generally also defines
the prefix for the link, and those need to be unique for routing to
work.
| If so is there any specific purpose for doing that ??
Not that I can think of.
| What about link-local address, how would it be used, if single link local
| address is configured on multiple interface of a same node.
This one is impossible to achieve. You can set addresses with the same
bit pattern, but they're all different addresses, as they're in different
scopes. Whether or not the bit patterns look similar, there's no great
magic to how LL addresses are used - if there's more than one possible
scope (ie: there's more that one interface, usually excluding the loopback
interface, that no-one I know of enables LL addresses on) then the scope
must always accompany the address for it to have any meaning at all.
in that sense, the scope is part of the address.
[Of course, if the multiple interfaces concerned were bridged together,
then they would all be in one link, all have one scope, and having just
a single LL address for the collection of them would make perfect sense].
