Setting the value of vRtrMplsP2mpInstResignal to 'doAction' triggers
the re-signaling 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 re-signal is triggered while a re-signaling 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'.
