- Reported by Paul Traina/cisco Systems
-
- Minutes of the Inter-Domain Routing Working Group (IDR)
-
- The IDR Working Group is the result of a merge between the Border
- Gateway Protocol Working Group (BGP) and the OSI IDRP for IP Over IP
- Working Group (IPIDRP). These minutes are from the joint session of BGP
- and IPIDRP that was held at the IETF in Toronto.
-
-
- Agenda
-
- o Agenda bashing
- o New group charter review
- o BGP-4 status update
- o BGP/OSPF interaction document
- o AS space growth
- o IDRP implementation report
- o Inter-domain routing for IPng
- o Deprecation of EGP
-
-
-
- New Group Charter Review
-
- The BGP and IDRP groups have been meeting in joint session for a long
- time. There was consensus that the two working groups should be merged
- into a single group which will handle the inter-domain routing area.
-
- Yakov and Sue were suggested as co-chairs for the new group and the name
- suggested by the attendees is ``Inter-Domain Routing Working Group'' or
- IDR Working Group.
-
-
-
- BGP-4 Document Status Update
-
- All current BGP-4 documents have been moved to Proposed Standard status.
- In point of fact, all requirements have been met to move BGP-4 to Draft
- Standard except that the six month timer in Proposed Standard status has
- not expired yet.
-
- Paul Traina will produce final documents (protocol analysis and
- operational experience) needed for advancing BGP-4 to Draft Standard.
- The documents could be based on similar documents produced for BGP-3
- (RFC 1265 and RFC 1266). Once BGP-4 reaches Draft Standard, it is
- expected that BGP-3 will become obsolete.
-
-
- BGP/OSPF Interaction Document
-
-
- Before this IETF, Kannan Varadhan updated the BGP-4/OSPF interaction
- document. No protocol or technical changes were made. Comments were
- made by several attendees that the new tables that were added made
- things more obscure.
-
- Suggestions are to be sent to Kannan over the next month. At the close
- of the comment period, the document will be revised (hopefully for the
- last time) and this revision will be moved to Proposed Standard.
-
- There are currently four reported implementations of BGP-4/OSPF
- interaction as described by this document: cisco, gated, Proteon, and
- Wellfleet.
-
-
-
- AS Space Growth
-
-
- There are currently 4000 AS entries allocated by the IANA out of a
- possible space of 65,535. Of these allocated entries, 400 of them
- currently appear in AS path tables as analyzed by Tony Bates. There is
- some concern that the AS space will be used up in the same fashion as
- the IPv4 address space. Things to be done:
-
-
- o Monitor AS usage and allocation growth
-
- o Instruct the IANA, NSPs and NICs to treat ASs as a finite resource
- and grant them according to a set of guidelines
-
- o Encourage vendors who suggest that all sites apply for an AS number
- to change their documentation
-
- o Further consideration of this issue to be referred to the CIDRD and
- ALE Working Groups
-
-
- John Hawkinson will coordinate with Tony Bates to write guidelines as to
- when AS numbers should be issued.
-
-
-
- IDRP Implementation Report
-
-
- David Jacobson presented a status report on a prototype IDRP
- implementation that was funded by the National Science Foundation and
- will be made publicly available shortly.
-
-
- IPng Transition
-
- The group reached clear consensus that BGP-4 will not be extended or
- modified for IPng, rather IDRP will be used as a basis for the IPng
- IDRP. IDRP will be used with the following changes:
-
-
- o IDRP's MULTI_EXIT_DISCRIMINATOR and LOCAL_PREF fields will be
- changed from one octet to four octets in length to match BGP-4.
-
- o A form of BGP-4's optional AGGREGATOR attribute will be added to
- IDRP.
-
- o IDRP will be changed to not prepend the local RD to the RD path
- until an advertisement is sent outside the current RD (a la BGP).
- If reason(s) can be found for this change between BGP and IDRP,
- this will need to be reviewed.
-
-
- Tony Li, Yakov Rekhter and Paul Traina will write the IDRP for IPng
- document. Dennis Ferguson will write a document describing constraints
- upon IDRP to ease the transition from BGP to IDRP/IP and eventually
- IDRP/IPng. Fred Baker, Dennis Ferguson and Paul Traina will produce a
- document that will be presented by the working group to the people
- working on IPng's IGPs listing desired features in an IGP that will
- improve IGP/IDRP cooperation (examples might include carrying RD path
- information, extending tag fields, etc.). Vadim Antonov has volunteered
- to write an Internet-Draft on security and authentication uses and
- requirements for an IDRP. A volunteer is needed to write an IDRP $ IGP
- interaction document covering both IPv4 and IPng.
-
-
- EGP
-
- Consensus among the group was to move EGP in all forms to Historic
- status. This will be conveyed to the IESG for appropriate actions.
