Description of Working Group:

The purpose of this working group is to define and develop a standard virtual router redundancy protocol for IPv4 and IPv6. A virtual router redundancy protocol is a protocol which allows several routers on a multiaccess link to utilize the same virtual IP address. One router will be elected as a master with the other routers acting as backups in case of the failure of the master router. The primary motivation to using a virtual router redundancy protocol is that host systems may be configured (manually or via DHCP) with a single default gateway, rather than running an active routing protocol. The protocol should also support the ability to load share traffic when both routers are up.

The goals of this working group are:

1. Define and develop a standard virtual router redundancy protocol for IPv4 and IPv6.

2. Develop VRRP MIB(s).

3. Separate specifications will be developed for IPv4 and IPv6.

4. Determine whether static (configuration based) load sharing is adequate or if some amount of dynamic load sharing is required.

5. Working group will examine security issues to determine what security threats it is appropriate for the VRRP protocol to handle and include the appropriate mechanisms in the VRRP protocol.

6. The internet draft "Virtual Router Redundancy Protocol" <draft-hinden-vrrp-00.txt will be use as the basis of virtual router redundancy protocol. The working group will also consider other internet drafts related to this topic allowing for issues regarding change control, security, running code, etc.

7. Intellectual property issues regarding the technology to develop a virtual router redundancy protocol will be identified and addressed.

Review Agenda

No modifications were made to the Agenda.

Interoperability Testing

Presented by Ray LaRoca, UNH

Held February 23, 24, and 25th at UNH's IOL

Participants: 3Com, Cabletron, Fore, IBM, Nokia, Xedia

The following tests were conducted:

Testing was successful. Misconfiguration problems resulted in text clarifications to the current draft.

VRRP Protocol Review

The changes made to the VRRP protocol in the current draft are:

Working group chair plans to issue last call for draft standard in next couple weeks.

There was a question regarding if there was anything to report regarding patent claims. Nothing new is known.


Presented by Brian Jewell, 3Com.

The current version of the MIB is 5. This did not make the IETF cutoff but a draft was available via anonymous ftp. The working group chair plans to issue last call for proposed standard when new draft is out as an ID.

The changes made to this version are
