IBM submits this Statement to the IETF dated April 15, 2003 for the IETF
RFC's (1) 2338, Virtual Router Redundancy Protocol, and (2) 2787,

IBM patent and patent application disclosures are based upon the working
knowledge of those individuals involved with the respective Technical
Working Group and do not represent the results of an IBM patent portfolio
search.

IBM believes the following issued patents may contain one or more claims
which may be relevant or facilitating to the compliant implementation of
the referenced RFC's and Internet Drafts.

US5371852: Method and apparatus for making a cluster of computers appear as
a single host on a network, Attanasio, and Smith, December 6, 1994.

IBM will, upon written request, provide a nonexclusive patent license, with
other reasonable and nondiscriminatory terms and conditions, for those
patents issued to IBM which contain claims related to compliant
implementations of the referenced RFC's / Internet Drafts and for which IBM
is able to provide patent licenses (including the patents disclosed above).
This patent license is available to all entities. If a party requesting a
patent license also has claims related to the implementation of the
Specifications, IBM will grant patent licenses only if the recipient, in
return, will grant IBM a reciprocal license, with substantially identical
terms and conditions, under the Requestorâ€(tm)s Claims.

Any party wishing to request an IBM patent license, in support of the IETF
RFC's (1) 2338, Virtual Router Redundancy Protocol, and (2) 2787,
