This read-only counter tallies the number of LSPs created on this node that originated from this particular interface of this node, meaning this interface serves as the LSP's ingress point. It tells an administrator how many MPLS-TE tunnels have been signaled starting at this specific interface over its lifetime, useful for identifying which access or edge ports are actively originating traffic-engineered paths. An unexpectedly high csRsvpIfIngressLspsCreated on an interface not meant to originate tunnels would prompt a check for a misconfigured or unauthorized tunnel source.
