Yes you are right it is very clearly saying -
"The Restart Counter value in the Recovery information element shall not be used, i.e. it shall be set to zero by the sender and shall be ignored by the receiver. The Recovery information element is mandatory due to backwards compatibility reasons."
So if we read the last sentence we can deduce that recovery is not needed. Now I assume this as that peer is restarted the local will either detect the peer failure by the way of path management or if it comes up well within the time local will not require any action.
Comments are welcome.
