This notification-carried object reports the name of the VPN routing instance associated with the LSP event. On a router hosting multiple VPN instances, such as in an MPLS L3VPN deployment, it lets the admin identify which specific VPN's LSP came up or went down, rather than assuming it's the default routing instance. A trap carrying jnxLdpInstanceName of customerA-vrf tells the admin the LSP event pertains specifically to that customer's VPN instance rather than the global routing table.
