A provider edge device may receive a first MAC/IP route advertisement that identifies a MAC route, or a MAC and IP route, relating to an endpoint device. The provider edge device may generate and provide a MAC/IP route proxy advertisement based on the MAC route or the MAC and IP route, detect a potential decrease in reliability of the MAC route or the MAC and IP route, broadcast a request to verify the reliability of the MAC and IP route, determine whether the reliability of the MAC route, or the MAC and IP route, has decreased, and perform an action to cause withdrawal of the MAC/IP route proxy advertisement, or to cause a second MAC/IP route advertisement that identifies the MAC route, or the MAC and IP route, to be provided, based on determining whether the reliability of the MAC route, or the MAC and IP route, has decreased.
