MINUTES
1. Milo Medin presented John Moy's slides of the Proteon OSPF
implementation in John's stead.
2. Rob Coltun presented slides of UMD's BSD OSPF implementation.
3. During the presentations questions came up concerning the migration
from RIP to OSPF. It was agreed that the best way to approach this is
to initially put OSPF at the borders of the Autonomous System and work
towards the center. We are considering writing a paper addressing this
issue.
4. Questions also came up regarding running OSPF on BSD systems that
currently do not support Multicast. We explained that the BSD version
allows configuring non-broadcast, multi-access networks over broadcast
networks to serve as a temporary fix for those systems that do not
support Multicast; this option will remain in the implementation until
Multicast is generally available.
5. There were discussions on conditions that may occur in very large
Autonomous Systems such as how to handle routing updates when a gateway
has run out of memory and on possible consequences of running the spf
algorithm each time a new LSA arrives when a partition has been
repaired.
6. We talked about some of the changes to the specification such as packet
formats, the Fletcher checksum, hello packets on non-broadcast
multi-access networks, and hello packets over point-to-point links.

7. We presented some possible MIB variables. These basically were state,
database and packet summary information. Not much discussion.
8. Some discussion followed about the OSPF working group being close to
(or at) the end. We talked about starting a Multicast routing working
group.
