Re: Vendor Private Extension

[Trevor Blackwell <[e-mail]>]

Could someone provide an example of a possible extension?  Right now I
can't imagine any very practical uses. What is it that might work
"better" between two brand-X routers?

If the extensions are for more detailed information, such as more
accurate cost or QOS descriptions, then maybe they should be made as
optional fields within the appropriate message elements, rather than
as top-level elements.

If the extensions are for fancy features, such as time/date dependent
routing or something, then it might make sense to implement these
entirely outside the scope of NHRP.

If there is some reasonable example, then I would definitely prefer to
see an explicit mechanism, rather than the time-honoured technique of
taking some message element that nobody else uses, and adapting it for
whatever special purposes.
