Abstract
There is a need for vendor-specific extensions to Mobility Header
messages so that Mobile IPv6 vendors are able to extend the protocol
for research or deployment purposes. This document defines a new
vendor-specific mobility option.

RFC 5094 MIPv6 Vendor Specific Option December 2007
1. Introduction
Vendor-specific messages have traditionally allowed vendors to
implement extensions to some protocols and distinguish themselves
from other vendors. These messages are clearly marked by a Vendor ID
that identifies the vendor. A particular vendor's implementation
identifies the vendor extension by recognizing the Vendor ID.
Implementations that do not recognize the Vendor ID either discard or
skip processing the message.
Mobile IPv6 [2] is being deployed and there is a need for vendor-
specific extensions to Mobility Header messages so that vendors are
able to extend the Mobile IPv6 protocol for research or deployment
purposes.
This document defines a new mobility option, the Vendor-Specific
Mobility Option, which can be carried in any Mobility Header message.
The Vendor-Specific mobility option MUST be used only with a Mobility
Header message. Mobility options, by definition, can be skipped if
an implementation does not recognize the mobility option type [2].
The messages defined in this document can also be used for NEMO [3]
and Proxy MIPv6 [4] since these protocols also use Mobility Header
messages.
Vendor-specific protocol extensions can cause serious
interoperability issues and may in addition have adverse operational
impact, if they are not designed and used carefully. The vendor-
specific option described in this document is meant to support simple
use cases where it is sufficient to include some vendor data in the
standardized Mobile IPv6 protocol exchanges. The vendor-specific
option is not suitable for more complex vendor extensions that modify
Mobile IPv6 itself. Although these options allow vendors to
piggyback additional data onto Mobile IPv6 message exchanges, RFC
3775 [2] requires that unrecognized options be ignored and that the
end systems be able to process the remaining parts of the message
correctly. Extensions that use the vendor-specific mobility option
should require an indication that the option was processed, in the
response, using the vendor-specific mobility option.
Vendors are generally encouraged to bring their protocol extensions
to the IETF for review and standardization. Complex vendor
extensions that modify Mobile IPv6 itself, will see large-scale
deployment or involve industry consortia, or other multi-vendor
organizations MUST be standardized in the IETF. Past experience has
shown that such extensions of IETF protocols are critically dependent
on IETF review and standardization.
