Setting the value of vRtrMplsP2mpInstResignal to 'doAction' triggers the resignaling of the P2MP LSP path. If the P2MP LSP path is operationally down either due to network failure or due to the retry attempts count being exceeded, setting this variable to 'doAction' will initiate the signaling for the path. A make-before-break signaling for the path will be initiated if the P2MP LSP is operationally up but the make-before-break retry attempts count was exceeded. Make-before-break signaling will also be initiated for any P2MP LSP that is operationally up. This may be used to cause a loose-hop P2MP LSP to be optimized. If a resignal is triggered while a resignaling is already in progress, the old transient state will be destroyed and a new transaction being triggered. An SNMP GET request on this object should return 'notApplicable'.
