In one embodiment, a plurality of first connections each couple a first distribution node of a first site to a respective access device. A second connection between the first distribution node and a first edge router is configured to not forward traffic associated with a first set of virtual local area networks (VLANs). It is determined whether the second distribution node is reachable from the first distribution node through the first edge router and a second edge router. The second distribution node is configured to forward traffic associated with the first set of VLANs to the second edge router. In response to a determination that the second distribution node is unreachable, the second connection is configured to forward traffic associated with the first set of VLANs. Traffic associated with the first set of one or more VLANs may be forwarded across the second connection to the first edge router.
