Sure I have read about ipv6 Ospf and ipv6 over frame-relay. But now I am
still a little bit confused about the link-local addresses:
look:
R1 - R2 when we configure ipv6 addresses on R1 interface and R2 interface
their serial interfaces have 2 ipv6 addresses one which we have configured
and 2nd which is link-local ipv6 address and it has it by default. Next we
can configure by ipv6 ospf 1 area 0 command ipv6 ospf between them. And sure
we configure frame-relay map ipv6 address for the ipv6 address which we have
configured: Now we have just normal ipv6 ospf configuration of ospf. (which
is documented in the doccd)
My question is in other thing.
1. How to be with link local addresses which they have by default. by ipv6
ospf 1 area 0 command they are also involved to the ospf. but untill
specially configured they can't be used because they have not frame-relay
map ipv6 command. But when we configure it, ipv6 ospf protocol is between
those addresses which we have configured and between link-local interfaces
as well.
In such a case should frame-relay map ipv6 also be configured for the
link-local address of the other side or not. And when configured what could
be the purpuse?? Because if not configured link-local addresses are just
unusefull there because they can't ping each other directly.
Just some of my thoughts about it.
What do you think??
Thaks,
