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.
This causes the venous blood pressure to increase and can stress the valves in the veins. Like crossing the legs, wearing heels can contribute to the overall venous reflux disease problem. You do not have to stop crossing your legs or wearing heels, but you should be aware of what you are doing.
