OSPF network type.
Per RFC 2740 (OSPF v3)
" When going from IPv4 to IPv6, the basic OSPF mechanisms remain
unchanged from those documented in [Ref1]. These mechanisms are
briefly outlined in Section 4 of [Ref1]. Both IPv6 and IPv4 have a
link-state database composed of LSAs and synchronized between
adjacent routers. Initial synchronization is performed through the
Database Exchange process, through the exchange of Database
Description, Link State Request and Link State Update packets.
Thereafter database synchronization is maintained via flooding,
utilizing Link State Update and Link State Acknowledgment packets.
Both IPv6 and IPv4 use OSPF Hello Packets to discover and maintain
neighbor relationships, and to elect Designated Routers and Backup
Designated Routers on broadcast and NBMA links. The decision as to
which neighbor relationships become adjacencies, along with the basic
ideas behind inter-area routing, importing external information in
AS-external-LSAs and the various routing calculations are also the
same."
So basically, same #$*# different protocol. :)

Hey Scott,
Thanks and I'll let Cisco know I appreciate the fact they're using as little
paper as possible to save our forests :-)
Also, when you say "non-broadcast" networks, you're referring to underlying
physical network as opposed to the ospf network type, right?
So, for example, if I'm using an ospf network type of point-to-multipoint
over a f/r network, do I still need the neighbor command or does this work
the same way as with ospf using ipv4?
Thanks again, Tim

This works pretty much the same as OSPFv2. With non-broadcast you need it.
Both sides is fine, but only one side is necessary.
They were just saving space by writing that document so thin on content. :)

Hi guys,
The Doc-CD says that when running ospf v3 on nbma networks, you must
configure the neighbor command but it doesn't elaborate.
Does this mean the neighbor command must be configured on both sides of the
vc and is this command required regardless of what type of ospf network is
specified?
TIA, Tim
