Abstract
A provider edge (PE) device may determine a first identifier, corresponding to a first connection for a first service, and a second identifier, corresponding to a second connection for a second service, where the first connection is between a first customer edge (CE) device and the PE device, and the second connection is between a second CE device and the PE device. The PE device may advertise a first route, associated with the first service, based on the first identifier and a label corresponding to a network instance. The PE device may advertise a second route, associated with the second service, based on the second identifier and the label. The PE device may determine that the first connection is unavailable, and withdraw advertisement of the first route, while maintaining advertisement of the second route, to indicate, to a remote PE device, that the first connection is unavailable.
