- DHC Minutes
-
- The meeting began with a presentation from Bill Nowicki of Legato about
- Legato's ``Network Resource Administration Platform''. Bill prefaced
- his talk with the statement that, while our Working Group is solving the
- low level problems associated with dynamic naming and addressing, his
- talk would cover more high level issues. The platform he described is
- intended to ease the use and management of network facilities for a
- running system.
-
- The remainder of the meeting concentrated on Jeff Mogul's ``Proposal for
- Supporting IP Address Assignment Using Coordinated BOOTP Servers''.
- Jeff has written up the IP address allocation and delivery mechanism as
- discussed at the June meeting in Palo Alto (see the PSC Proceedings for
- details). A copy of Jeff's proposal is available for anonymous FTP on
- sol.bucknell.edu in file dhcwg/mogul.prop.
-
- The discussion raised several specific questions about the proposed
- protocol:
-
-
- o The protocol must not require a server on each subnet.
- o There should be a new response ``No IP address available''.
- o A client can release an IP address back to the IP address server -
- can the client also clear ARP caches of any references to that
- client?
- o How can a client find out that its IP address has been reallocated
- after a network partition heals?
- o Rather than periodically pinging a host to verify that its IP
- address is still in use, the IP address servers should only check
- when IP addresses need to be reused.
- o We need to write into the protocol description something about the
- eventual use of multicast.

-
- Steve Deering was good enough to go through the Host Requirements RFC
- and generate a list of per network and per interface parameters. He
- wondered if we should consider any of these as part of the dynamic host
- configuration protocol:
-
- Per network parameters:
-
-
- Gateway forwarding on/off
- Non-local source routing on/off
- Policy filters for
- non-local source routing (list)
-
- 1
-
-
-
-
-
-
- Maximum reassembly size integer
- Default TTL integer
- PMTU aging timeout integer
-
- Per interface parameters:
-
- Perform mask discovery on/off
- Be a mask supplier on/off
- Perform router discovery on/off
- Router solicitation
- multicast address (multicast address)
- Ignore router discovery on/off
- Default router list (addresses and preferences)
- Static routes:
- destination (host/subnet/net)
- mask (subnet mask)
- type of service integer
- first hop router (address)
- ignore redirects on/off
- PMTU integer
- perform PMTU
- discovery on/off
