    HI Team, 

    Bypass Tunnel (Many to one) : - During a Failure, Path and RESV messages from HE to Tail end router and vice-versa  are tunneled across bypass LSP to maintain the state of Protected LSP . 

    I have a question regarding FRR one-to-one detour LSP (Link or Node protection ) . in  case of failure (link or node)  how does  the PLR and MP maintain the state of Protected LSP (Path and RESV message required to refresh the state)  ?
