You will not be able to dig out the roots so you have to treat the plant with a weedkiller that will travel down through the plant to the roots - it will kill the whole plant.
Don't cut down the plant until you can see signs that it is beginning to die (probably several weeks after you apply the weedkiller). If any parts of the ivy start to grow back treat it with Glysophate again. Sometimes you will need to re-treat tough plants like ivy several times in order to kill them off. Follow directions on the packet. Be aware that Glysophate will kill any plant that it touches.
