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 parameters. -Ejay -----Original Message----- From: David Scott Olverson [mailto:olverson@fas.harvard.edu] Sent: Thursday, December 19, 2002 11:10 AM To: nanog@merit.edu Subject: Using link congestion to control routing updates Hello all, I was wondering if anyone was aware of a way to use the congestion of a network link to control the routing update. For example if I have a very small link that gets congested, I may want the router to withhold a routing update until link congestion falls below a certain threshold like 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
