Using link congestion to control routing updates

IIRC, and I may be wrong, either IS-IS or CLNS (can't remember which)
can look at congestion, and EIGRP can look at load if you tweak the K

Subject: Using link congestion to control routing updates

Hello all,

	I was wondering if anyone was aware of a way to use the
of a network link to control the routing update.  For example if I have
very small link that gets congested, I may want the router to withhold a
routing update until link congestion falls below a certain threshold
60% of bandwidth.  Is anyone aware of anything like this available today
or a technique that might accomplish something similar?  You can contact
me off list if this topic isn't germane.

Thanks for your help,

Dave Olverson
