In other words, RIP is a soft state protocol. Every route has a property called a metric, which indicates the distance to the route's destination. Every time a router receives a route advertisement, it increments the metric.
Venous reflux disease, also known as venous insufficiency, is a medical condition affecting the circulation of blood in the lower extremities. Normally, one-way valves in the veins keep blood flowing toward the heart against the force of gravity. When the valves become weak and do not close properly, they allow blood to flow backward and this is a condition called reflux.
Several factors can contribute to the venous reflux that causes edema: 1  Genetics â Determines more than anything else whether a patient will develop vein disease. 2  Obesity or weight gain â Excessive weight causes vein disease to progress more quickly.
