 the discovery transport address, but for VyOS MPLS LDP to work both parameters
 must be explicitly set in the configuration.
 
+Another thing to keep in mind with LDP is that much like BGP, it is a protocol that
+runs on top of TCP. It however does not have an ability to do something like a
+refresh capability like BGPs route refresh capability. Therefore one might have
+to reset the neighbor for a capability change or a configuration change to work.
