Description
Enable LDP downstream on demand on the LDP session. LDP is widely deployed in downstream unsolicited advertisement mode. As service providers integrate the access and aggregation networks into a single MPLS domain, LDP downstream on demand is needed to distribute the bindings between access and aggregation networks to minimize the workload for the access node (AN) control plane and to avoid the storage of tens of thousands of label bindings from upstream aggregation nodes.
