Opposite problem -- he wants to delay routing updates if the link is full. EIGRP by default won't use more than 25/50% (I forget) of link bw, for instance, but I'm not aware of any intentional features in other IGPs to do this. If routing updates constitute enough traffic to disrupt your links, you need to investigate why you have so many updates instead of putting a band-aid on the problem. S Ejay Hire wrote:
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. -----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 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.
